摘要
提出了一种用于ABS滑移率控制的滑模变结构控制方法,通过将实际滑移率与参考滑移率作比较,形成滑动面,追踪参考滑移率来使ABS系统处于制动的最佳区域。并且采用了饱和函数来削弱变结构带来的颤抖现象,经仿真表明,该方法在ABS的滑移率控制中是切实有效的。
The design of a sliding mode control for the purpose of controlling wheel slip is described in this paper.The control objective is to track a reference input wheel slip.The design strategy investigated is based on a sliding surface that contains the error between the reference input wheel slip and the actual one.The design uses saturation function to reduce libration in the system response.Simulations are performed to demonstrate the effectiveness of the proprosed sliding mode controller.
