One solution is to add a rotor position sensor to the synchromotor. 解决这一问题普遍的做法是加装电机转子位置传感器。
There are some errors in the indirect rotor position estimation method of SRM, So performance of the rotor can't be well controlled by general control policies. 摘要由于电机间接转子位置角度估计方法中存在一定误差，采用一般的控制策略难以实现电机性能的良好控制。
