Research on Improved Active Disturbance Rejection Control of PMSM Based on a Novel Parameter Tuning Algorithm

In order to improve the performance of the PMSM motor control system against the inward and outward disturbance, this paper proposes an improved control scheme based on the active disturbance rejection control (ADRC) with genetic algorithm (GA) as automatic parameter tuning mechanism. This improved ADRC controller increases the current response by compensating the time delay of the feedback path. Besides, by taking advantage of the self-learning ability of GA and multiple iterative calculations, a group of optimal parameters can be achieved, thus the difficulty of parameter tuning for ADRC can be reduced. Simulation and experiment are also carried out to verify the improved controller's performance and validity.
