N2 - The permanent magnet synchronous motor (PMSM) adopts the current vector control method with id = 0 to achieve current decoupling of the d-q axis during static processes. However, this method does not solve the problem of strong current coupling in the dynamic process of the motor system, especially in the transition process of sudden load, where the dynamic coupling of current has a more serious impact, resulting in a deterioration of the motor’s dynamic performance. This article summarizes the d-q axis current decoupling control methods for PMSM based on diagonalization decoupling, compares and analyzes the five current decoupling strategies included, and provides a d-q axis control model diagram for each decoupling method. By analyzing their respective control principles and transfer function characteristics, the conditions for achieving dynamic complete decoupling of current are given. Finally, simulation were conducted to compare the parameters of the PMSM under two operating conditions: complete matching and mismatch. The correctness of the theoretical analysis results was verified, and dynamic decoupling of the current loop was achieved.
