摘　　要：利用ADAMS/Car软件建立某轿车的多刚体动力学模型,并分别提出滑膜变结构控制、PID控制、模糊控制三种控制策略,通过Matlab软件中的Simulink构建控制模块,联合ADAMS/Car建立的轿车多刚体动力学模型进行控制对比仿真试验。仿真结果表明:所采用的控制策略是有效的,可有效改善汽车操纵稳定性;同时,通过比较发现,三种控制策略各有优缺点,从控制效果来看,滑膜变结构控制相对要好一些,但PID控制模型简单,不需要精确的数学模型且易于实现。The multi-rigid-body dynamics model of a car was established with ADAMSCar and three control methods including variable structure control with sliding mode,PID control and fuzzy control were proposed respectively.Combined with the Simulink program of software Matlab,the simulation and comparison experiment of established model was carried out and the result showed that the adopted control strategy was effective,which could improve the handling stability of vehicles obviously.Meanwhile,three control methods all had advantages and disadvantages through comparison.The effect of variable structure control is better than others,but PID control model is simple and easy to conduct without accurate mathematical model.
