A Permanent Magnet Synchronous Motor Vector Control System Based on DSP for Sensorless Speed Control

A solution to control a permanent magnet synchronous motor(PMSM) of sensorless using the TMS320LF2407 is discussed. In the text, a brief introduction of the mathematic model and the vector control of PMSM is presented, and the method of ascertain the rotor position under the circumstances of speed sensorless is also mentioned. The control method of =0 on salient pole PMSM which is sensorless is put forward, it shows that if using the digital signal processor we can make the complicated vector control arithmetic come true easily, and can also resolve the coupling characteristic of motor effectively.
