摘　　要：对转子表贴式永磁同步电机(PMSM)提出了无传感器的驱动策略。基于非线性估计方法,准确估计了转子位置与转子速度,即使系统在瞬态下,估计仍然是准确的。由于该估计系统不含永久磁铁建立的磁链,因此无传感器驱动策略对磁链变化具有鲁棒性。实验结果验证了该方案的可行性。The authors propose a sensorless drive scheme for a permannent magnet sychronous motor （PMSM） using a non-linear estimation method.With the non-linear estimation method,the actual rotor position as well as rotor speed can be obtained even in transient state.Due to the estimation is irrespective of the flux linkage established by the permanent magnet,the sensorless drive system has robustness to the flux linkage variations.Experimental results validate the proposed scheme.
