摘要
针对1/4空气悬架模型,设计了一多输入多输出的模糊控制器,对空气悬架系统空气弹簧刚度和减振器阻尼进行集成控制,并利用MATLAB/SMULINK软件进行仿真研究。从结果中可以看出,与被动空气悬架比较,该控制策略下的空气悬架能降低簧上质量加速度,具有较好的鲁棒性,使车辆平顺性有一定程度的提高,为空气悬架的集成控制提供了理论依据。
A multi-input multi-output fuzzy controller was designed based on the quarter-car dynamic model,To integrated control the air-spring stiffness and the shock absorber damper,The dynamic simulation model of the fuzzy control suspension was built up by MATLAB/SIMULINK.The simulation results show that compared with the positive air suspension,the fuzzy controlled air suspension could be used to reduce the sprung mass acceleration with better robustness,and improve ride comfort.The study has provided the academic reference to the integrated control of air suspension.
