摘　　要：针对常规指数趋近律变结构控制的抖振,提出一种改进型指数趋近律变结构控制方法,并应用于汽车防抱死制动系统(ABS)的控制器设计.应用MATLAB/Simulink建立仿真模型,验证该控制器的有效性,并给出单一路面和跃变路面的仿真结果.研究结果表明,汽车ABS的改进型指数趋近律的变结构控制能有效减小抖振,且保持常规变结构控制的鲁棒性和快速响应性.For the chattering problem of variable structure control based on exponential reaching law,a variable structure control based on improved exponential reaching law has been proposed and applied in the design of ABS controller.MATLAB/Simulink modeling and simulation have been employed to verify the effectiveness of the proposed controller on single road and variational road.The results show that the variable structure control based on improved exponential reaching law can effectively reduce the chattering and keep the robustness and quick response capability of the conventional variable structure control.
