摘　　要：在线性二自由度车辆模型的基础上,以PID控制、模糊逻辑控制理论为基础,运用不同的控制策略,基于直接横摆力矩控制方法,利用Simulink设计了车辆操纵稳定性控制器,进行了控制效果的仿真分析和比较。仿真结果表明:单独控制质心侧偏角、以及对质心侧偏角和横摆角速度进行联合控制,控制效果要优于单独的横摆角速度控制;模糊逻辑控制具有较强的鲁棒性而PID控制具有较强的应用性。Two degrees of freedom vehicle dynamic model is established. Based on theories of PID control and fuzzy logic control, controller of vehicle stability is designed by using the method of direct yaw moment control and the different control strategies. By comparing and analyzing control effect of PID control and fuzzy logic control, the result shows as follows： slip angle and yaw rate combined control is better than slip angle and yaw rate controlled individually by comparing control effect;fuzzy logic control have a better robustness and PID control is simple and practical by analyzing control theories.
