摘要
利用滤波白噪声法和车轮相关性,建立了车辆非平稳行驶条件下四轮相关路面输入模型,研究了汽车在非平稳行驶状态下的动态响应。提出了自适应模糊控制、模糊PID控制和模糊免疫PID等复合控制方法,并应用于汽车半主动悬架系统控制。仿真分析车辆在非匀速情况下随机路面的响应情况可知,当汽车处于非平稳行驶工况时,3种复合控制算法均具有很好的控制效果,且控制性能优于传统模糊控制。
The filtered white noise and wheels correlation theories in vehicle are used to establish the non-stationary random input model with four wheels correlation.The dynamic response of vehicle under non-stationary running condition is studied.Adaptive fuzzy logic,fuzzy proportional Integration differential(PID) and fuzzy immune PID control strategies are proposed and applied to vehicle semiactive suspension system control.Simulation results show that the proposed compound control strategies such as adaptive fuzzy,fuzzy PID and fuzzy immune PID demonstrate much better ride comfort and handling performance than the conventional fuzzy logic control when nonstationary running condition is applied.
