摘　　要：通过分析传统模糊PID控制器的不足之处,提出一种增强型多参数半主动悬架模糊PID控制器;与传统模糊PID控制器相比,该控制器可将路面条件变化考虑进去,并基于路面条件的变化实现变论域和PID控制器控制参数的二次调整,弥补了传统模糊PID控制器输入参数过于单一的缺点。建立了车辆二自由度1/4模型,并在Matlab/Simulink平台中建立相应的仿真模型;通过对被动悬架系统、模糊PID控制系统和增强型多参数半主动悬架模糊PID控制系统仿真分析,证明了增强型多参数半主动悬架模糊PID控制系统的先进性。By analyzing the shortcomings of traditional fuzzy PID controller,an enhanced multi parameter fuzzy PID controller for semi-active suspension was proposed.Compared with the traditional fuzzy PID controller,this controller can take the change of road condition into account,and based on the change of road conditions,it can change the universe and realize the secondary adjustment of PID controller control parameters,which makes up for the shortcomings of the traditional fuzzy PID controller with single input parameters.The two degree of freedom 1/4 model of vehicle was established,and the corresponding simulation model was established in Matlab/Simulink platform.Through the simulation analysis of the passive suspension system,fuzzy PID control system and an enhanced multi parameter fuzzy PID control system for semi-active suspension,its advanced nature was proved.
