摘要
以某微型客车悬架的液压减振器为研究对象,依据汽车动力学理论建立了1/4汽车半主动悬架控制系统的动力学模型,并应用MATLAB/Simulink软件及模糊控制理论模拟仿真了客车在C级路面以不同速度行驶时的振动特性。研究结果表明:模糊控制器可以进一步提高客车的乘坐舒适性和操纵稳定性,同时验证了其具有良好的鲁棒性。
A hydraulic bumper of a micro-coach suspension was chosen as the research object.According to vehicle dynamics theory,the dynamic model of 1/4car semi-active suspension control system was set up.We used MATLAB/Simulink software and fuzzy control theory to simulate the vibration characteristics when the coach rode on C-road at different speed.The results show that the fuzzy controller can improve the vehicle ride comfort and handing stability,and the fuzzy controller has good robustness.
