This paper introduces a novel regression methodology for terrain modeling that can approximate arbitrarily complex functions based on a series of simple kernel calculations, using variational Bayesian inference. A sparse feature vector is used to efficiently project input points into a high-dimensional reproducing kernel Hilbert space, according to a set of inducing points automatically generated from clustering available data. Each inducing point maintains its own regression model in addition to individual kernel parameters, and the entire set is iteratively optimized as more data are collected in order to maximize a global variational lower bound. We also show how kernel and regression model parameters can be jointly learned, to achieve a better approximation of the underlying function. Experimental results show that the proposed methodology consistently outperforms current state-of-the-art techniques, while producing a continuous model with a fully probabilistic treatment of uncertainties, well-defined gradients, and highly scalable to large-scale datasets. As a practical application of the proposed terrain modeling technique, we explore the problem of trajectory optimization, deriving gradients that allow the efficient generation of continuous paths using standard optimization algorithms, minimizing a series of useful properties (i.e. distance traveled, changes in elevation, and terrain variance).

In this paper, we proposed an autonomous navigation method for unstructured environments based on terrain constraints. Efficient path search and trajectory optimization on octree map are proposed to generate trajectories, which can effectively avoid various obstacles in off-road environments, such as dynamic obstacles and negative obstacles, to reach the specified destination. We have conducted empirical experiments in both simulated and real environments, and the results show that our approach achieved superior performance in dynamic obstacle avoidance tasks and mapless navigation tasks compared to the traditional 2-dimensional or 2.5-dimensional navigation methods.

They are key features for the navigation of an unmanned ground vehicle (UGV) in a non-planar environment. In this work, a 3D light detection and ranging (LiDAR) sensor is used to obtain the geometric information about a rough terrain surface. For a given SE(2) pose of the vehicle and a specific vehicle model, the SE(3) pose of the vehicle is estimated based on LiDAR points, and then a traversability is computed. The traversability tells the vehicle the effects of its interaction with the rough terrain. Note that the traversability is computed on demand during trajectory planning, so there is not any explicit terrain discretization. The proposed trajectory planner finds an initial path through the non-holonomic A*, which is a modified form of the conventional A* planner. A path is a sequence of poses without timestamps. Then, the initial path is optimized in terms of the traversability, using the method of Lagrange multipliers. The optimization accounts for the model of the vehicle’s suspension system. Therefore, the optimized trajectory is dynamically feasible, and the trajectory tracking error is small. The proposed methods were tested in both the simulation and the real-world experiments. The simulation experiments were conducted in a simulator called Gazebo, which uses a physics engine to compute the vehicle motion. The experiments were conducted in various non-planar experiments. The results indicate that the proposed methods could accurately estimate the SE(3) pose of the vehicle. Besides, the trajectory cost of the proposed planner was lower than the trajectory costs of other state-of-the-art trajectory planners.

However, the integrated spacing policies aim to maximum overall benefit, and the distributed spacing policies intense to get optimal monomer benefit. Ignoring the fairness of the benefit allocation of each vehicle will reduce the motivation to constitute the platoon. To fill this critical gap, this study proposes a spacing allocation method by treating spacing decisions as cooperative games. A flock’s model which is used to be the payoff function is introduced based on bionic motion principles. We present a characteristic function of the platoon for the cooperative game model considering the specific structure of the platoon. The τ value, Shapley value, and average lexicographic value are introduced and applied to allocate the spacing fairly. Proposed methods are compared with constant distance policy in some typical situations. The simulation results demonstrate that the spacing policy based on cooperative game theory improved the stable time for consistency control and the convergence of longitudinal following error.

(in Chinese) DOI: 10.12382/bgxb.2021.0824 http://doi.org/10.12382/bgxb.2021.0824 To deal with the problems of fuzzy road features and complex terrain in off-road environment, a road traversability analysis method for unmanned tracked platforms is proposed based on the fusion scheme of camera and lidar for sensing. Firstly, the semantic point cloud is obtained based on image semantic segmentation, and the passable area is roughly extracted. Then the three-dimensional point cloud is used to describe the ground geometric features, and road traversability is analyzed considering the trafficability constraints of the tracked platform. Finally, a three-dimensional traversable grid map containing road surface attributes and ground geometry information is generated. The definition of platform traversability in the proposed method reflects the strong coupling relationship between the platform and the environment. The experimental results show that the algorithm can stably establish the traversable map, provide good guidance for platform planning and control, and is conducive to the stable trafficability of the unmanned tracked platform in the complex off-road environment.

(in Chinese) DOI: 10.3901/JME.2020.23.021 http://doi.org/10.3901/JME.2020.23.021 During the walking of a legged robot, the interactions between its end of feet and the terrain strongly affect the traversability of the robot. Foot-terrain interaction is closely related to the geometry of the terrain surface and the physical characteristics of it. Therefore, path planning based on geometric map alone is difficult to meet the demand of avoiding non-geometric hazards such as soft sand in the wild. To solve this problem, an environment model including geometric and physical characteristics is proposed in consideration of foot-terrain interaction for path planning of legged robots. By simplifying and unifying the foot-terrain interaction model under soft and rigid terrain, parameterized indexes characterizing the normal softness and tangential friction characteristics of the terrain are proposed, and a more comprehensive environment model is constructed by combining geometric characteristics and the proposed physical characteristics. Comprehensively considering the ground geometric and physical characteristics affecting the robot's traversability, the optimization target of path planning is reconstructed and the optimal path is planned for legged robots with graph search algorithm. Simulation and experiments with the hexapod robot Elspider verified that the proposed method can effectively avoid non-geometric hazards and plan a safer and more reliable path to traverse.

(in Chinese) DOI: 10.12382/bgxb.2021.0832 http://doi.org/10.12382/bgxb.2021.0832 To improve the performance of unmanned tracked platforms in complex off-road environment, this study proposes a semantic information-based method to integrate the environment perception, motion planning and motion control modules of the unmanned system. Through the fusion perception method of camera and lidar, image semantic information and lidar point cloud features are obtained by the environment perception module, and then the traversable area is roughly determined by combining geometric parameters of the platform. Finally, a three-dimensional grid map with different traversability information is generated, after the Gaussian clustering model is used to conduct a fine traversability analysis of the environment in the traversable area. Platform kinematics and dynamic constraints are considered in the motion planning module. On the basis of smooth transition constraints, terrain and road surface attributes are taken into account to generate behavior motion primitives, and the trajectories with behavior semantics are generated using hierarchical online selection of primitives. The motion control module is based on model predictive control which considers the execution ability, tracking deviation, and control stability of the platform drive motor. Based on the semantic attributes of the behavior motion primitives provided by motion planning, the weight coefficient of the control objective function is updated in real time to reduce lateral deviation, heading deviation, and speed deviation of trajectory tracking. Finally, the medium-sized hybrid unmanned tracked platform is used for verification. The results show that the motion planning method proposed in this paper are 46.1%, 46.5% and 14.2% lower in average pitch angle, average roll angle and average curvature than the trajectory planning result using the plane binary grid map. Compared with the motion control method with fixed parameters, the proposed variable-parameter motion control method based on behavior semantic trajectory reduces the lateral deviation, heading deviation, and speed deviation by 17.1%, 2.7% and 6.1%, respectively.

The analytical method and the solution idea of sequential decoupling are adopted. Firstly, the random dynamic load of the quarter vehicle model under random unevenness excitation is derived. Then, with the help of relative coordinate transform and Fourier integral transform, the analytical solution for the dynamic response of the viscoelastic multilayered asphalt pavement subjected to the random dynamic moving load is derived based on the wave propagation method, and the numerical program is compiled. Through analyzing the example of vehicle-pavement dynamic response, it can be found that the dynamic response amplitude of the asphalt pavement at each longitudinal position along the vehicle moving direction is related to the random dynamic load. Through the parameter analysis of vehicle-pavement system, it can be found that reducing the suspension and tire stiffness coefficients, or increasing the suspension damping coefficient can reduce the longitudinal strain at the bottom of the asphalt layer, which is beneficial to improve the pavement fatigue life; Tire damping coefficient has almost no effect on pavement dynamic response; The deterioration of pavement unevenness can significantly exacerbate pavement fatigue damage; Increasing the vehicle moving speed can reduce the average value of longitudinal strain at the bottom of the asphalt layer, but increase its variation coefficient, thus the effect of the vehicle moving speed on the average value and variation coefficient of the dynamic response should be comprehensively considered to evaluate the pavement fatigue life accurately.

Based on the Weierstrass-Mandelbrot(W-M) function and the definitions of power spectral density(PSD) and coherence function,the analytic coherence relation of the phase angles in the components of fractal model for the left and right wheels is derived. The 2D road roughness fractal models which considers on the phase angle coherence and the Cholesky decomposition of PSD matrix of road roughness are established, respectively,by combining with W-M fractal function and the Cholesky decomposition of PSD matrix of road roughness with different wheelmarks.Theoretical research shows that the road simulation method based on W-M fractal function is equivalent to the harmonic superposition method for γ→1.The fractal model based on the Cholesky decomposition of PSD matrix of road roughness is a universal model,and the fractal model based on the coherence of phase angle is a special case of the above model. Simulated results show that the auto-PSDs of the two models are in good agreement with the corresponding reference PSD,and the accuracy and credibility of the two models are verified consequently for γ→1.

(in Chinese) DOI: 10.3969/j.issn.1000-1093.2019.07.002 http://doi.org/10.3969/j.issn.1000-1093.2019.07.002 A novel dynamic co-simulation methodology is presented to establish a mechanical-electrical-hydraulic integrated dynamic model of marching tank for studying the nonlinear vibration of marching tank under high mobility conditions. A property hydraulic subsystem model is established in Amesim, a tank mechanical system model, in which several nonlinear factors, such as barrel flexibility, are considered, is builded using RecurDyn, and a control system model is also builded using MATLAB/Simulink. A calculation program of the three-dimensional road roughness considering the coherence of left and right tracks was created using the sinusoid superposition method. The calculated results show that the muzzle vibration amplitude is larger than that of cradle because of barrel’s flexibility. When the road roughness is small and the running speed is low, the muzzle bends downward relative to the cradle. With the increase in road roughness and running speed, the stability of hull and cradle is getting worse, and the stabilizer cannot guarantee the stabilization accuracy. The difference of elevation angular displacement between muzzle and cradle caused by barrel’s flexibility is significantly reduced. Therefore, the influence of barrel’s flexibility on the firing accuracy cannot be solved by static correction simply, and the driving condition should be considered. Key

Proceedings of the Institution of Mechanical Engineers Part C-Journal of Mechanical Engineering Science , 2019 , 233 ( 9 ): 3038 - 3049 . DOI: 10.1177/0954406218802315 http://doi.org/10.1177/0954406218802315 Tank stabilizer is a control system keeping the bore axis in the desired sighting angle. For the control problem of the stabilizer in the case of uncertain parameters, the adaptive control method is introduced to design the vertical tank stabilizer with the nonlinear dynamic model of vertical stabilizer given in the paper. In the design, the multiple parameter uncertainties of the hydraulic servo system are fully considered and the linear feedback control is used to improve the asymptotic stability of the system. The vertical stabilizer of tank is simulated in MATLAB/Simulink environment. In addition, a dynamic model of tank on the move is established based on multi-body system theory, vehicle terramechanics and gun launch dynamics. Then the established dynamic model is combined with the designed controller based on the RecurDyn/Control module. The numerical calculation results show that the adaptive control method can effectively control the muzzle vibration of tank on the move and it can satisfy the requirement of actual vertical stabilization accuracy. But some nonlinear factors of the gun such as the flexibility of the barrel will seriously influence the desired stabilization accuracy of the vertical tank stabilizer. A comparison experiment between adaptive control and proportional-integral-derivative control is also presented to show the effectiveness of the adaptive control method. The research provides a feasible way to improve the firing accuracy of tank firing on the move.

The hydraulic system model was modeled in Amesim and the dynamic model of marching tank was established in RecurDyn based on multi-body system theory, vehicle terramechanics, and gun launch dynamics. The control system model was modeled in MATLAB/Simulink. Therein, the adaptive robust control algorithm was introduced to design the vertical stabilizer controller and the simulation program of the designed controller was developed by C language. The simulation results show that the muzzle vibration of marching tank can be controlled effectively by the ARC method. Furthermore, the muzzle error compensation signal was added in the designed controller to weaken the detrimental effect of the barrel flexibility on muzzle vibration. This work provides an approach to investigate the dynamic behavior of marching tank considering effects among the mechanical, hydraulic, and control subsystems.

(in Chinese) DOI: 10.12382/bgxb.2021.0295 http://doi.org/10.12382/bgxb.2021.0295 A self-stabilizing control method for gun line based on interference rate compensation in geodetic coordinates is proposed to achieve the high precision stability and tracking control of gun under the conditions of moving base and high firing angle. The proposed method can used to effectively restrain the influence of self-propelled artillery attitude disturbance on the gun line pointing. According to the motion law of stable gun line on a moving base,a mounting mode of interference rate measuring gyro is designed,and the decoupling compensation values of the azimuth and pitching interference rate in geodetic coordinates are derived. On the basis of the traditional anti-aircraft gun servo principle,the interference rate feed-forward compensation is applied to realize the self-stabilization and control decoupling of gun line. Since the gun stability is only related to two degrees of freedom of turret rotation and gun pitching,both of which have eccentricity moment and other factors. The Newton-Euler approach is used to establish a dynamic model of moving carrier,gun and turret. The nonlinear stiffness and backlash of transmission mechanism are considered combined with the executive motor model and classical closed-loop control. The control strategy is simulated in the two cases of ignoring elasticity and considering elasticity,respectively,under the conditions of three-axis compound swaying with the heading,pitching,rolling amplitudes of 7° and period of 2 s of vehicle body. The simulated results show that the proposed stability control method with interference rate compensation is used to achieve the stable firing angle of more than 60°,the stability control error of less than 0.5 mrad and the sinusoidal stability tracking control error of less than 2.8 mrad,and the control decoupling of pitching an azimuth is realized.

An electromechanical co-simulation model of servo system is established, and the PID parameters are tuned using intelligent optimization algorithm. A servo control system model considering the attitude disturbance of moving body is established, and an electromechanical joint simulation model of servo system is established by combining with the upper mounting virtual prototype. The method of real vehicle test is used to verify the correctness of the joint simulation model. On this basis, the integral of time multiplied by the absolute value of error is used as the optimization objective function, and the PID parameters are tuned using the differential evolution algorithm (DE), and compared with the original model control parameters and the genetic algorithm (GA) tuning parameters. The joint simulation results show that,compared with the original model control parameters, the RMS value and standard deviation of the axis of firepower control error are reduced by 24.06% and 25.20%, respectively, by using the PID parameters tuned by the differential evolution algorithm for simulation, and the convergence speed is faster than that of genetic algorithm. The modeling method and parameter tuning method are effective and feasible, and have theoretical reference value for the optimization of the control accuracy axis of firepower.

However, the integrated spacing policies aim to maximum overall benefit, and the distributed spacing policies intense to get optimal monomer benefit. Ignoring the fairness of the benefit allocation of each vehicle will reduce the motivation to constitute the platoon. To fill this critical gap, this study proposes a spacing allocation method by treating spacing decisions as cooperative games. A flock’s model which is used to be the payoff function is introduced based on bionic motion principles. We present a characteristic function of the platoon for the cooperative game model considering the specific structure of the platoon. The τ value, Shapley value, and average lexicographic value are introduced and applied to allocate the spacing fairly. Proposed methods are compared with constant distance policy in some typical situations. The simulation results demonstrate that the spacing policy based on cooperative game theory improved the stable time for consistency control and the convergence of longitudinal following error.

Such a feasible space does not possess expansiveness, a property that characterizes whether planning queries can be solved efficiently with traditional probabilistic roadmap (PRM) planners. In this paper we present a new PRM-based multi-modal planning algorithm for problems where the number of intersecting manifolds is finite. We also analyze the completeness properties of this algorithm. More specifically, we show that the algorithm converges quickly when each submanifold is individually expansive and establish a bound on the expected running time in that case. We also present an incremental variant of the algorithm that has the same convergence properties, but works better for problems with a large number of submanifolds by considering subsets of submanifolds likely to contain a solution path. These algorithms are demonstrated in geometric examples and in a legged locomotion planner.
