Abstract：In order to compensate the control delay of active power filter (APF), a current predictive algorithm based on horizontal filter is presented. Reference current for next control cycle is predicted by horizontal filter with Widrow-Hoff learning algorithm, and predictive current control of APF is realized with space vector pulse width modulation (SVPWM) method. The equivalent structure of APF system with predictive current control is built, and it is decomposed into two parts. Lyapunov function is established for the stability analysis of current predictive algorithm, and transfer function of APF with SVPWM method is used to analyze the stability of SVPWM part. Long-term stable operation and compensation results of APF prove the effectiveness of control algorithm and the correctness of stability analysis for APF.
