Abstract
To improve the performance of permanent magnet synchronous motor sensor less control system, the phase offset caused by the low pass filter must be considering. In this paper, to apply the linear control theory to PMSM system. The introduced control strategy is based on reduced-order observer and adaptive velocity estimation, then proposed a method to compensate the phase offset by group time delay. With proper pole locations of the observer, stability of the position estimation is guaranteed, and stability of the adaptive velocity estimation is also guaranteed by Popov's hyper stability theory. The effectiveness of the method is verified through the SIMULINK modeling and simulation.
