摘　　要：基于直接横摆力矩控制方法,设计了一种前馈—反馈补偿控制的车辆稳定性控制器。其中控制器以4WS为期望的车辆模型,通过前馈补偿控制可使车辆的质心侧偏角趋于理想值,而反馈补偿控制可使车辆模型在较好地跟踪理想模型的基础上,有效抵抗外界干扰。通过前轮角阶跃输入与正弦输入仿真,就控制效果的稳定性与对前轮转角的跟随特性两方面而言,所设计的控制系统能较好地控制车辆的操纵稳定性。Based on direct yaw moment control （DYC） method, the vehicle stability controller with a feedforward and feedback compensator is designed. In the controller, the 4WS is the desired vehicle model. By the feedforward compensator, the value of vehicle sideslip angle at center of gravity can tend to desired value and the feedback compensator can not only trace the desired model but also resist the outside disturb effectively. With the analysis of stability control effect and following characteristic, the simulation experiments of front angle step and sine indicate that the designed controller can improve the vehicle handling and stability better.
