摘要
针对简化的汽车纵向双轮模型,将参数自整定模糊PID控制器应用于ABS系统,并且可以在线调整参数,使系统具有较好的稳定性、自适应性和控制精度,进一步缩短了制动距离和制动时间。比常规的PID控制器或模糊控制器,可以达到更好的控制效果。滑移率校正器根据系统运动状态自动调节系统的期望滑移率,提高了控制系统的稳定性。在M at-lab/S imu link环境下对系统进行了仿真分析。
Aiming at the simplified double - wheel vehicle model, the parameter self- tuning fuzzy PID controller was applied to the ABS system, which realizes the modification of the parameters on line, makes the system have better stability, adaptability and control precision, shortens the braking distance and the braking time. Compared to the normal PID controller or the fuzzy controller, the finer control result was attained. The slip ratio corrector equipment can adjust the anticipant slip ratio according to the running state of system, which improves the stability of the control System. A simulation analysis was presented under Matlab/Simulink environment.
