【摘要】 以电动小汽车的轮毂直驱方式为对象,基于永磁同步电机状态空间模型,设计了鲁棒控制器,应用于电动汽车驱动控制。将基于鲁棒控制设计的系统与基于最优控制的系统进行了比较。仿真结果表明,采用鲁棒控制的永磁同步电机系统响应速度快,控制性能好,对负载变化和自身参数扰动具有较好的鲁棒性,能够很好地满足电动汽车的性能要求。更多还原

【Abstract】 Based on the state-space model of permanent magnet synchronous motor(PMSM),the robust H∞controller of PMSM used in electric vehicle is proposed.The control system on the base of robust H∞control theory is compared with that based on optimal control theory.And the simulation results show that the controller has the advantages of rapid response,accuracy control and strong robust stability for the change of load and parameter perturbation,and can meet the electric vehicle’s demands.更多还原
