LADRC Control for the Three-Phase Voltage-Type PWM Rectifier

摘要：

　　In the three-phase voltage-type pulse width modulation (PWM) inverter system,the steady DC-bus voltage is significant for normal operation of PWM converter.With traditional control method,DC-bus voltage has poor anti-disturbance performance and large steady-state error generated by parametric uncertainties of inductive resistance and switching devices equivalent resistance.To cope with these problems,a linear active disturbance rejection control (LADRC) controller is designed based on the advantages of the LADRC in processing system internal perturbation and external disturbance.The simulation study shows that under the same disturbance the proposed method can realize not only faster dynamic response and better property of anti-disturbance performance,but also unity power factor control.For the uncertainties of AC equivalent resistance and inductance,the method shows strong adaptability and robustness.
