Taking the nonsalient-pole permanent magnet synchronous motor (PMSM) as research object, the responding model of PMSM with high-frequency pulse voltage injection is built, then, the square-wave voltage pulse injection method based on high-frequency vibration is researched, and the angle and rotational speed of rotor are estimated by calculating trigonometric function. Comparing to conventional high-frequency sinusoidal voltage signals injection method for observing the rotor position, it is effective to real-time observe the rotor angle, improve the control bandwidth of the system and accelerate the rapid response performance with less low-pass filter. The simulation results verify the feasibility and effectiveness of this method.
