Three phase rectifier unbalanced power grid MPC model prediction+ADRC self disturbance rejection

Three phase rectifier unbalanced power grid MPC model prediction+ADRC self disturbance rejection control simulation
Control strategy:
(1) Model Predictive Control: A low switching frequency operation algorithm based on sequential model predictive control. Adopting the concept of sequential model predictive control, a dual evaluation function is designed to reduce the switching frequency of the rectifier while reducing the distortion rate of the grid side current, and minimizing the fluctuation of active or reactive power.
(2) ADRC self disturbance rejection control: Due to the long transient time of traditional FCS-MPC during system variable load operation, it affects system performance. The self disturbance rejection controller is used to improve the voltage outer loop of the system, enhancing its robustness and enabling faster recovery from transient to steady state. The effectiveness of the algorithm is verified through simulation.
