摘　　要：建立了2自由度1/4车辆的半主动悬架模型,并设计了模糊PID控制器。在输入信号为滤波白噪声随机路面输入的条件下,使用Matlab/Simulink仿真软件对模糊PID控制的半主动悬架系统进行仿真。仿真结果表明,模糊PID控制的半主动悬架系统相比PID控制的悬架系统,其车身加速度、悬架动挠度和轮胎动行程都有明显的降低,车辆行驶时的平顺性和稳定性有了很大提高。A semi-active suspension model of 2-degree-of-freedom 1/4 vehicle is established, and a fuzzy PID controller is designed. Under the condition that the input signal is filtered white noise random road input, the semi-active suspension system of the fuzzy PID control is simulated by using Matlab/Simulink simulation soft- ware. The simulation results show that the semi-active suspension system with fuzzy PID control has a signifi- cantly lower PID control system, and the vehicle body acceleration, suspension dynamic deflection and tire dy- namic stroke are obviously reduced.
