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。
Aiming at the torsional vibration of electric vehicle transmission system, the control of transmission system is studied based on hybrid μ integrated robust control theory. The uncertainty model of a centrally driven pure electric vehicle transmission system considering the uncertainties of high order non-modeling and the perturbed parameters of the PMSM is established. The μ-method is used to design the robust controller of the transmission system. In Matlab / Simulink software environment In the simulation calculation to verify the effectiveness of the design of the controller. The results show that this control strategy can make the system obtain strong robustness and robust stability and reduce the possibility of system instability effectively.
