Parameters Identification of PMSM Based on Recursive Least Squares

For the change of the electromagnetic parameters of the running PMSM,recursive least squares method and the deduction of the steady-state model of PMSM were used to identify the resistance and inductance of the motor online.The accruacy was proved by the comparison and analysis in Matlab/Simulink.It has great practical value because of the reliability and easy implement of recursive least squares.
