摘　　要：研究了基于横摆角速度反馈的汽车四轮转向控制系统.首先把汽车简化成一个二自由度的两轮车模型,建立了线性二自由度四轮转向车辆的动力学模型.然后设计了基于横摆角速度反馈控制四轮转向系统,并给出了控制算法.最后通过MATLAB/Simulink对其进行了仿真验证,相比较两轮转向,四轮转向控制的汽车系统具有更好的动态特性.The four wheel steering control system based on yaw rate feedback is studied. Firstly, the vehicle is simplified into a two wheel model with two degrees of freedom, and a dynamic model of a linear two degree of freedom four wheel steering vehicle is established. Then, the four wheel steering system based on yaw rate feedback control is designed, and the control algorithm is given. Finally, the simulation is carried out by MATLAB/Simulink, and compared with the two wheel steering, the four wheel steering control system has better dynamic characteristics.
