Synchronous motor excitated magnet by direct current can make output mechanism specialities matched load specialities by means of adjusting exciting current to change magnetic field and power factor.
For AC servo system of permanent magnet synchronous motor (PMSM), the position servo controller was constructed with direct torque control and self-adjusting PI control based on Fuzzy inferences.
在永磁同步电机交流伺服系统中，采用直接转矩控制及模糊自适应PI控制构成位置伺服控制器。
