Modeling and simulation of parameter identification for PMSM based on EKF

In this paper, on the basis of vector control, Extended Kalman Filter (EKF) was employed to estimate stator winding resistance, rotor flux-linkage due to permanent magnet and temperature rise in stator winding and rotor magnet of AC PMSM. Identification model of different parameter was established in rotating reference frame and MATLAB/SIMULINK was used to do simulation experiments. The theoretical analysis and identification models were confirmed to be correct and effective by the simulation results.
