An Improved Method for Direct Torque Control System

In order to reduce torque ripples in direct torque control (DTC) permanent magnet synchronous motor (PMSM) system, space vector modulated (SVM) DTC based on active-disturbance rejection control (ADRC) was put forward. ADRC speed regulator was designed. The achievement of SVM was analyzed to accurately compensate the error of stator flux and torque. Simulation results have shown that torque ripples are dramatically reduced, and the robustness of the system is improved.
