| 摘 要： | 以汽车空气悬架系统为研究对象,建立了1/4空气悬架模型以及路面白噪声模型,将模糊控制理论和PID控制策略经过有机结合后运用于半主动空气悬架系统控制,并利用MATLAB/Simulink软件进行了仿真研究。通过仿真结果对比表明,与单纯的PID控制、模糊控制相比,在该联合型模糊PID控制策略下的半主动空气悬架能更好地降低车身垂直加速度和悬架动挠度,具有较好的鲁棒性,使车辆行驶平顺性也具有一定程度的提高。

| Abstract: | One quarter air suspension model and the white-noise road model are established by taking the air suspension system of car as a study case in it,the dynamic integration between the fuzzy control theory and PID control strategy is applied to active control of the air suspension system.At the same time simulation study is carried out by utilizing MATLAB/Simulink,which results shows that,compared with the traditional PID and the fuzzy control,the control of the semi-active air suspension may reduce the sprung ... |
