| 摘 要： | 首先提出一个非线性控制系统研究汽车转向系统和防抱死制动系统的协同控制问题。该控制结构由转向控制器和制动控制器组成。为了确保系统全局稳定性,采用反馈线性化方法进行解耦。为了提高系统的鲁棒性并确保期望的动态性能,对解藕线性化的系统采用内模控制方法进行综合。然后设计适用于复杂工况的制动力分配策略。最后用仿真结果验证控制系统的有效性,它改善了汽车制动稳定性和转向性能。

| Abstract: | Firstly,a nonlinear control system was proposed for the cooperative control of the vehicle’s steering and antilock braking systems.The control architecture is composed with the steering controller and the braking controller.The system was decoupled through feedback linearization method,which ensured the global stability of the system.In order to guarantee the dynamic desired property and to improve the robustness of the system,the internal model control method was applied to the decoupled and linearized system.Then the brake force distribution policy applicable to the complex work condition was proposed.Finally,the validity of the control system was validated by simulation results,which improved the braking stability and steering performance. |
