MRA based Speed and Rotor Position Estimation Strategy for the SPMSM

摘要

In this paper, a novel model reference adaptive (MRA) based speed and rotor position estimation strategy is proposed for the surface mounted permanent magnet synchronous motor (SPMSM). In the proposed strategy, a new adaptive law is proposed by considering the MRA adaptive law as a controller. Furthermore a parameter self-turning strategy and a speed compensation strategy are proposed to improve the performance of the MRA method. Finally simulation results, which are obtained by the MATLAB/Simulink software, are presented to verify the feasibility and effectiveness of the proposed strategy.
