摘　　要：针对2自由度的1/4车辆半主动悬架模型,以被动悬架系统为参考模型,运用模糊控制方法设计了半主动1/4车悬架的模糊控制器。设计了3个输入和输出变量,在MATLAB/Simulink里建立了以模糊推理规则为基础的控制器,路面输入采用白噪声,仿真结果表明,该控制方法可以很好的降低车辆悬架的簧载质量的垂直加速度,以便提高车辆的平顺性和舒适性。As to 1/4 Vehicles emi-active suspension with two degrees of freedom, utilizing fuzzy control method to design semi-active 1/4 Vehicle suspension, this model was used to tracking the passive model. There are three variables of input and output in this model.Building the controller which is based on fuzzy reasoning matrix, and the road excitation adopt white noise.The simulation result show that the fuzzy control reduce the vertical acceleration of suspension, and it improve the harshness and riding comfort of Vehicle.
