针对增程式电动汽车行驶时因不确定性路面扰动导致车速出现波动的问题,设计自适应鲁棒车速跟踪控制器,使汽车跟踪理想车速,通过Matlab/Simulink仿真软件验证所设计自适应控制器算法的有效性。仿真结果表明,该控制器可以自适应调节控制增益,对路面环境未知扰动的不确定性具有良好鲁棒性。研究成果可为增程式电动汽车的车速跟踪控制设计提供参考。

For the extended range electric vehicle,the vehicle speed may fluctuate due to the uncertainty of road disturbances.In view of this problem,an adaptive robust vehicle speed tracking controller is designed to enable the extended range electric vehicle speed to track the ideal value.The validity of the algorithm of the designed adaptive controller is verified by Matlab/Simulink simulation software.Simulation results show that the controller can adaptively adjust the control gain,and has good robustness against the uncertainty of unknown road surface environment disturbance.The simulated results can provide a reference for the design of speed tracking control of range-extended electric vehicles.
