滑模控制方法在汽车防抱制动系统中的应用研究

ABS性能优劣的关键在于控制方法的选取，提出了一种基于ABS滑移率控制的滑模变结构控制方法。该方法通过选定合适的切换甬数和控制规律，可以迫使系统沿设计的滑移面做滑模运动。从而使防抱制动系统的滑动模态对系统的动理学变化、参数变化、外部干扰具有很强的鲁棒性和自适应性。将这一控制方法应用于单轮车辆模型，在MATLAB／Simulink环境下进行仿真。仿真结果表明，滑模控制方法在ABS的滑移率控制中是切实有效的，能够明显提高汽车ABS的性能。

The study on the application of the changed slip form structure control method in the ABS

Elaborating a control method based on the automobile ABS slip ratio controlled slip form structure ,by means of the proper exchanging function and control regulation, forcing the system move along the designed slip surface so that the ABS system slip form have a good LB character and selfadaptability for the dynamics changing ,function changing and outside interference, emulating under the MATLAB/Simulink environment. The result proves that slip form control method is effective in the ABS slip ratio, improving the ABS performance significantly.
