Speed Regulation Strategies of PMSM Based on Adaptive ADRC
Abstract:
To the speed-regulation system of permanent magnet synchronous motor (PMSM), this paper presents a active disturbances rejection controller (ADRC) based on the adaptive theory. First, the inertia information will be obtained by identification. Then, ADRC is designed by combining an adaptive algorithm. The controller can realize the adaptive parameters adjustment according to the inertia information, which is called adaptive ADRC. Simulation results have confirmed this control strategy can effectively improve the stability and robustness of PMSM.
