Abstract
A decoupling control system for a salient pole synchronous motor that includes a harmonic current detection module, configured to acquire 6k±1 harmonic current feedback; a linear transformation module, configured to perform linear transformation on 6k±1 harmonic current references and 6k±1 harmonic current feedback in a harmonic reference frame separately to acquire new harmonic currents; and a harmonic current decoupling control module, configured to make adjustment according to an error between a harmonic current reference subjected to the linear transformation and harmonic current feedback subjected to the linear transformation, and perform independent decoupling control over each of the harmonic currents.
