Direct Torque Controlled Permanent Magnet Synchronous Motor Based on Active Disturbance Rejection Controller

摘要

The speed regulator based on active disturbance rejection control is designed against the shortcomings of PID regulator. The transition process for a given speed is got by tracking - differentiator. The contradiction between the system response speed and overshoot is overcome. The system disturbance is observed through the extended state observer and compensated for real-time, thus anti-jamming capability is improved. The nonlinear control is achieved through nonlinear state error feedback; therefore, the control precision is improved. Permanent magnet synchronous motor direct torque control based on ADRC is realized. The simulation results have shown the feasibility and effectiveness of this method.
