考虑悬架几何特性及作动器延时的整车模糊控制

Fuzzy Control about Whole Vehicle Considering Suspension Geometry and Actuator Time Delay

利用ADAMS软件建立了整车悬架及转向机械模型,考虑了悬架的几何特性,结合变论域模糊控制方法,设计了主动悬架变论域模糊控制器,同时考虑了作动器的延时特性,通过matlab/simulink联合仿真,并与被动悬架模型进行了对比,得出所设计的模糊控制器对汽车的平顺性有较大改善。

By building the steering and suspension mechanical model of the vehicle by ADAMS,considering the suspension geometry and combining with the variable domain fuzzy control method,the active suspension variable domain fuzzy controller was designed while taking the actuator delay character into account. Using Matlab/Simulink,the contrastive research was done with the passive suspension model. The simulation tests indicate that the designed fuzzy controller can improve the ride performance of vehicle greatly.
