摘要：
In this paper, an improved model reference adaptive system (MRAS) method is proposed, taking the flux linkage free permanent magnet synchronous motor (PMSM) model as a reference model to identify stator resistance and stator inductance online. The negative impact of permanent magnet flux linkage error on other parameters identification is avoid. According to MATLAB/Simulink simulation, the proposed parameter identification method can achieve high identification steady accuracy and dynamic response, which proves the effectiveness of this method.
