摘　　要：运用模糊控制理论在所建立的车辆非线性模型的基础上,设计了用于车辆横向稳定性的3种模糊控制器———基于横摆角速度的反馈控制、基于质心侧偏角的反馈控制以及基于这两个参数的联合反馈控制,并应用MATLAB/S imu link对所设计的3种模糊控制器分别进行了仿真分析,结果表明,3种控制器均能改善车辆的横向稳定性,能够提高车辆行驶的安全性,并且,联合控制的控制效果要优于单独控制。The three types of fuzzy controllers, which are feedback control of yaw rate, feedback control of side slip angle, and joint feedback control of yaw rate and side slip angle, respectively, are designed to improve the lateral stability of vehicle. They are based on fuzzy control principle and established non-linear vehicle model. The performances of three types of control systems are evaluated through MATLAB/Simulink simulation and analysis. The results indicate：the three types of controllers all can improve vehicle lateral stability;the effect of joint controller is significantly better than the other two controllers.
