摘　　要：利用ADAMS建立了1/4车辆主动悬架的机械模型,运用MATLAB设计了基于自适应模糊PID控制算法的主动悬架控制系统,通过ADAMS/Control模块与MATLAB的接口实现了基于车辆悬架多体模型的主动控制联合仿真。仿真结果表明,采用自适应模糊PID控制能取得很好的控制效果,与被动悬架相比显著地降低了车身加速度和轮胎动位移,大大提高了车辆的乘坐舒适性和操纵稳定性。A mechanical model of quarter vehicle active suspension was established by using ADAMS. A controller for active suspension based on adaptive fuzzy PID control algorithm was designed by using MATLAB. Finally, the actiw, control cosimulation based on vehicle suspension multi-body model was carried out through the port between ADAMS/Control module and MATLAB. The simulation results indicated adopting adaptive fuzzy PID control could achieve satisfying control effects. Compared to passive suspension, it reduced the body acceleration and tire dynamic displacement evidently, and greatly improved the ride comfort and handling stability of the vehicle.
