摘　　要：针对电动车传动系统的扭转振动问题,基于混合μ综合鲁棒控制理论对传动系统控制进行研究。建立考虑永磁同步电机高阶未建模不确定性和参数摄动的某集中驱动式纯电动车传动系统不确定性模型;采用μ方法设计传动系统鲁棒控制器;在Matlab/Simulink软件环境中进行仿真计算,以验证所设计控制器的有效性。结果表明,该控制策略能够使系统获得较强的鲁棒性能与鲁棒稳定性,有效降低系统失稳的可能性。In view of the torsional vibration of an electric vehicle（EV） driveline,based on the blendingμ integrated robust control theory,the control method of driveline is studied.Firstly,the driveline uncertainty model of a central-driven pure EV is established,considering the high-order unmodeled uncertainty of permanent magnet synchronous motor and the parameter perturbation.Then,μ-method is adopted to design the driveline robust controller.Finally,in order to verify the validity of the designed controller,the simulation and calculation are conducted by using Matlab / Simulink.Results show that the control strategy can enhance the robust performance and robust stability of the system,and reduce the possibility of system instability effectively.
