Sliding Mode Control of Permanent Magnet Synchronous Motor Speed Regulation System Based on FxTSMC-ESO
In order to improve the dynamic performance and robustness of the speed control system of a permanent magnet synchronous motor(PMSM)and address the problem of external load disturbances in the speed loop,this paper proposes a control method based on a novel fixed-time sliding mode controller and an extended state observer.The proposed sliding mode controller simplifies the convergence time for-mula and solves the contradiction between fast response and vibration suppression.To further enhance the robustness of the speed control system,a fixed-time convergent extended state observer is used to provide feedforward compensation for disturbances in the controller.This observer not only reduces the switching function gain of the approaching law but also achieves accurate disturbance observation.Simulation results demonstrate the effectiveness of the proposed sliding mode control method.
