Overview of Active Disturbance Rejection Control for Permanent Magnet Synchronous Motors

The ubiquitous implementation of permanent magnet synchronous motors (PMSMs) in contemporary alternating current propulsion systems is widely acknowledged. As a superior control method that does not rely on a precise system mathematical model and has superior robustness, Active Disturbance Rejection Control (ADRC) is widely used to improve the overall control performance and efficiency of the PMSM drive system. Starting from three parts of ADRC, this paper comprehensively expounds on the advantages of the ADRC control strategy and its shortcomings in the application at present. The problems of too many parameters, not easily controlling the nonlinear part, and difficulty in adjusting the parameters are summarized. Then the performance improvement schemes of ADRC such as structure optimization, parameter tuning, nonlinear part optimization, and simplified parameters are summarized. Finally, the future development trend of the control algorithm is forecasted.
