【摘要】 针对电动汽车永磁同步电机无位置传感器控制系统,在两相静止坐标系(α-β)内将滑模观测器法与MRAS结合,提出了基于模型参考自适应的滑模观测器,并利用自适应律估计永磁同步电机的转子速度。仿真和试验表明无位置传感器控制方法是切实可行的。更多还原

【Abstract】 This paper presents a new adaptive slid-mode observer for electric vehicle permanent magnet synchronous motor(PMSM) sensorless control system,which is combined with the sliding mode observer and model reference adaptive method in the two-phase stationary reference frame.The speed of PMSM rotor is estimated by adaptive law.Simulation and experimental results show that the sensorless control method is practical and feasible.更多还原
