Abstract In order to compensate control delay of active power filter (APF), a predictive current control strategy based on ADAptive LInear NEuron (ADALINE) for three-phase APF is proposed. Reference compensation current for next control cycle is calculated by current predictive algorithm based on ADALINE, and reference voltage is determined according to APF mathematical model in two-phase static coordinate system. The output current of APF can track to reference current quickly and exactly by space vector pulse width modulation (SVPWM) method. Simulation and experimental results on APF prototype demonstrate that, compared with APF of SVPWM control without predictive algorithm, APF with predictive current control strategy based on ADALINE has higher steady state compensation accuracy and better dynamic performance.
