摘要
"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。
The ‘boundary layer' method is considered as a kind of commonly and effective variable structure control with sliding mode for automotive ABS. Although the ‘boundary layer' method may weaken the chattering of the system, the merit of robustness of variable structure control with sliding mode is eliminated at the meantime. In view of this shortcoming, an improved exponential approach law of variable structure control with sliding mode method was proposed, which has the merit of the small chattering and good robustness, Simulation study was performed to variable structure control with sliding mode system adopting the improved exponential approach law for automotive ABS. And the simulation results illustrate that the method is effective to automotive ABS control.
