摘要
针对滑模变结构控制方法能较好地解决汽车防抱死制动系统的非线性问题,以及其固有的抖动会影响控制效果的问题,本文采用一种基于指数趋近律的滑模控制方法,设计了两轮车辆的防抱死制动系统滑模控制器,并在Matlab/S imu link里进行了仿真。仿真结果表明了该控制策略可以有效地抑制传统滑模控制系统的抖动现象,达到更好的控制效果。
A sliding mode based variable structure controller is designed for anti-lock braking system to solve the problem of the strong nonlinearity of tyre dynamics. The inherent drawback of sliding mode control is chattering in its application,which will affect the control performance greatly. Thus, in this paper sliding control based on exponential approach law has been adopted to weaken chattering, and the idea simulations are done in Matlab/Simulink. The results show that this strategy is feasible and effective and can also restrain the chattering phenomenon of the control system better.
