摘要: 针对双电机耦合驱动履带车辆转向动力学模型具有多输入多输出(MIMO)、非线性且参数不确定的特点,对系统进行解耦,分解为车速控制系统和转向角速度控制系统。在车速控制系统中为实现车速跟踪误差的收敛,根据期望车速与当前速度信息,提出了鲁棒滑模变结构控制算法;在转向角速度控制系统中,提出了针对转向角速度的模糊滑模自适应控制算法。通过“驾驶员—控制器”在环的双电机耦合驱动履带车辆实时仿真系统,对控制算法进行了仿真实验验证,证明了该控制算法的有效性。

Abstract: Steering dynamic model of double motor coupling drive transmission for tracked vehicle has the features of MIMO, parameter-uncertainty and nonlinearity. The steering system is transformed into a forward speed control subsystem and a steering speed control subsystem by dynamic decoupling control algorithm.For the forward speed control subsystem, a robustness sliding mode control algorithm is proposed to converge the speed errors based on the desired speed and the current speed. For the steering speed control subsystem, a steering speed control algorithm is designed based on the fuzzy adaptive sliding-mode algorithm to ensure the tracking control of the reference steering speed. The steering tracking control is verified by real-time simulation system.The results show that the proposed control algorithm is effective.
