  • Decoupling control system and method for harmonic current of salient pole synchronous motor
    Patent number: 11705842
    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.

  • METHOD AND SYSTEM FOR DETECTING HARMONIC CURRENT IN SYNCHRONOUS MOTORS
    Publication number: 20210223295
    Abstract: The present invention relates to a method and a system for detecting the harmonic current in synchronous motors. The method includes the following steps: (1) extracting the total stator current harmonics based on the control error between the reference value of fundamental stator current and the feedback value of stator current in the d, q coordinate; (2) using a plurality of synchronous coordinate transformations and low-pass filters to extract each harmonic to be detected from the total harmonic current.
