“边界层”法被认为是一种常用的有效的汽车ABS滑模变结构控制方法。“边界层”法虽然可以削弱系统的抖振,但是它同时也消除了滑模变结构控制的鲁棒性的优点,针对这一缺点提出了采用改进的指数趋近率的滑模变结构控制方法,该方法具有抖振小及良好的鲁棒性的优点。对采用该指数趋近率的汽车ABS滑模变结构控制系统进行了仿真研究。仿真结果表明,该方法在汽车ABS的控制中是有效的。
“Boundary layer ” method is considered as a commonly used and effective control method of automobile ABS sliding mode variable structure. Although the boundary layer method can weaken the chattering of the system, it also eliminates the robustness of the sliding mode variable structure control. In view of this shortcoming, a sliding mode-change with an improved exponential approach rate Structure control method, the method has the advantages of small buffeting and good robustness. The simulation study of automotive sliding mode variable structure control system based on the approaching rate of the index is carried out. Simulation results show that this method is effective in the control of automobile ABS.
