| 摘 要： | 建立了基于电子机械制动（EMB）系统的车辆单轮动力学模型，针对制动过程的非线性特征和路面条件的复杂性，设计了基于滑移率的滑模变结构控制器以充分利用地面的附着力及适应制动的全工况要求，并采取了相应的措施削弱抖振现象.在单路面与变路面条件下的仿真计算验证了滑模控制器的可行性和有效性，同时也表明滑模变结构控制器的控制性能及对路面的适应性均优于PID控制器.

| Abstract: | In order to study the characteristics of the state-of-art Brake-by-Wire (BBW) systems, the structure and model of the electromechanical brake (EMB) actuator was discussed. Then, in terms of the nonlinear properties of the braking process and the complexity of road conditions, the dynamics of quarter vehicle was presented. Finally, to regulate the slip-ratio of the vehicle under brake while making use of the friction provided by the road, a sliding mode controller (SMC), which was able to control chatter, was designed and computer simulation was studied under Matlab/Simulink. The results have shown the feasibility of the proposed sliding mode controller, and its comparison with PID controller has demonstrated its advantages over PID controller. |
