Research of active disturbance rejection control for efficiency optimization of induction motors

  • For problems of complex control algorithms of existing efficiency optimization control method of motor, an improved dynamic decoupling control strategy based on active disturbance rejection controller was proposed. The active disturbance rejection controller leave out differential tracker, and adopts linear expansion of state observer and linear state error feedback control law, so that the control algorithm can be simplified. The results of simulation and experiment show that the control strategy can ensure efficiency optimization of the motor under light loading operation, which has strong anti-interference ability and robustness, improves dynamic response speed of the motor in efficiency optimization process.
