摘要

为提升特种车辆快速起竖驱动控制的精准性和平稳性，针对双级液压缸驱动的重载起竖系统的强非线性、模型不确定性和换级碰撞动态，提出一种基于神经网络的电静液起竖系统换级碰撞补偿积分鲁棒控制方法。以电静液直驱的五铰点起竖系统为研究对象，建立考虑起竖机构运动机理、换级碰撞动力学及泵控系统压力流量动态的状态空间方程；采用改进的L-N接触模型对非线性碰撞力进行前馈补偿，同时设计神经网络逼近未建模的碰撞及摩擦动态，从而构建完整的第二通道模型前馈补偿项，针对匹配及不匹配的不确定性设计双通道的积分鲁棒控制律加以克服；基于Lyapunov稳定性理论证明电静液五铰点起竖系统的半全局渐近跟踪性能。通过AMESim-Adams-Simulink联合仿真对比实验，验证所提方法的有效性。研究结果表明：恒功率中速起竖工况和快速起竖工况下NNRISE+CFC控制器的稳定精度分别为0.0073°和0.0095°，相较于其他控制策略，换级时的推力波动得到明显抑制，具有较高的控制精度和运动平稳性。

Abstract

To improve the accuracy and stability of the rapid erection control of special vehicles

a neural network-based robust integral of the sign of error（NNRISE）control method is thus proposed for the electro-hydrostatic erection system with inter-stage collision compensation. In this method

the strong nonlinearity

model uncertainty and inter-stage collision dynamics of heavy-duty erection system driven by the two-stage hydraulic cylinder are taken into account. Taking the five-hinge erection system directly driven by the electro-hydrostatic actuator as the research object

the state-space equations are established considering the erection mechanism kinematics

the inter-stage collision

and the pressure-flow dynamics of pump-controlled system. The feedforward compensation for nonlinear collision force is achieved using a modified L-N contact model. Meanwhile

a neural network is designed to approximate the unmodeled collision and friction dynamics. This integrated approach is used to establish a comprehensive feedforward compensation term for the second channel. Subsequently

the dual-channel RISE control laws are developed to address both matched and unmatched uncertainties. The semi-global asymptotic tracking performance of the electro-hydrostatic five-hinge erection system is proved based on Lyapunov theory

and the effectiveness of the proposed method is verified through the AMESim-Adams-Simulink co-simulation. The research results show that the stability accuracies of NNRISE with collision force compensation（NNRISE+CFC）are 0.0073° and 0.0095°

respectively

under the conditions of constant-power medium-speed erection and rapid erection. Compared with other control strategies

the thrust fluctuation during stage-changing is significantly suppressed

which achieves high control accuracy and motion stability.
