Abstract: In order to accurately identify the parameters of the permanent magnet synchronous motor, a parameter identification method based on the variable regularization parameter affine projection algorithm was proposed.The mathematical model of the permanent magnet synchronous motor in the d,q coordinate system was analyzed.The parameter identification model was contructed based on the affine projection algorithm.The optimized variable regularization parameter affine projection algorithm was used to realize the parameter identification. Simulation proves that the method can accurately identify motor parameters. The optimized parameter identification method reduces the steady-state error on the basis of ensuring the convergence speed.

Key words: permanent magnet synchronous motor(PMSM), parameter identification, variable regularization parameter, affine projection algorithm(APA)
