Abstract：A solution based on predictive repetitive control was proposed to address the problem of reduced

robustness in active power filter（APF）systems during grid voltage distortion. Firstly，a mathematical model of

APF under weak grid conditions was established，and a repetitive factor was introduced to construct a model for

suppressing grid voltage distortion. On this basis，a predictive control algorithm was used to calculate the control

vector for the next step，and the accuracy and dynamic response speed of the controller were improved by

modifying the current reference method. This method suppresses the sudden change of model parameters caused by grid voltage distortion from the model level，thus enhancing the robustness of the predictive controller. Finally，the effectiveness and practicality of the proposed method were verified through simulation and experiments.
