摘要
利用Simulink软件建立车辆的四分之一主动悬架和路面的仿真模型,基于PID控制原理和模糊控制原理分别设计以车身垂向加速度为控制对象的PID控制器和模糊控制器,对主动悬架系统进行仿真。对比被动悬架系统、PID控制的主动悬架系统和模糊控制的主动悬架系统的仿真结果,结果表明PID控制和模糊控制的主动悬架系统都能明显改善车辆的行驶平顺性及乘坐舒适性,在控制效果上模糊控制优于PID控制。
Firstly, simulation models of the 1 / 4 automobile active suspension and road are established by the Simulink soft-ware; Secondly, the PID controller and fuzzy controller are designed and targeted at the vertical acceleration based on the PIDcontrol strategy and fuzzy control strategy so as to simulate the active suspension system. Comparing the simulation results ofpassive suspension system, active suspension system of the PID control and of the fuzzy control, it is shown that the active sus-pension system of PID control and that of fuzzy control can both improve the vehicle ride comfort, while the fuzzy control isbetter than the PID control in control effects.
