【摘要】 针对可调刚度和阻尼的主动悬架,建立1/4车辆悬架动力学模型。借鉴免疫原理,结合模糊控制规律,设计了一种模糊免疫PID控制器。应用Matlab/Simulink控制系统软件进行计算机仿真。仿真结果表明,具有模糊免疫PID控制器的主动悬架的控制结果明显优于常规的模糊PID控制,提高了车辆乘坐舒适性和操纵稳定性。更多还原

【Abstract】 A1/4 vehicle suspension mathematical dynamic model is established for the active suspension with the adjustable stiffness and damping.According to the immune principle and the fuzzy control rules,a fuzzy immune PID control method is designed.The paper completes simulation analysis for the whole system by using Matlab/Simulink software.Results show: the fuzzy immune PID control is superior to the usual fuzzy PID control on active suspension.Ride comfort and handling stability are improved greatly.更多还原
