摘　　要：以滑模控制、线性二次型最优控制以及PID控制三种控制理论为基础,运用不同的控制策略,基于直接横摆力矩控制方法,设计了车辆稳定性控制器,并进行了控制效果的仿真分析和比较。就控制策略而言,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,在车辆运行的大多数工况下,控制效果要优于单独控制横摆角速度;就控制理论而言,滑模控制具有较强的鲁棒性和应用性。由于稳定性控制器应重点对低附着系数路面上的车辆进行控制,针对研究对象的运行工况,滑模控制下的质心侧偏角控制和联合控制策略具有明显的优越性。Based on the three control theories： sliding mode control, linear quadratic optimum control and PID control, the vehicle stability controllers are designed using direct yaw moment control law with different control strategies, and the control effects are analyzed and compared in the simulation. Considering the control strategy, the control effect of controlling the sideslip angle singly and combined control are better than that of controlling the yaw rate singly. And about the control theory, the sliding mode control has better adaptability and application. Because the stability controller should mainly work on low adhesion coefficient road, focusing on the driving condition of research object, the control strategies of sideslip angle and the combined control with sliding mode have remarkable superiority.
