ADAPTIVE CURRENT CONTROL METHOD FOR HYBRID ACTIVE POWER FILTER

Minh Thuyen Chau

   This paper proposes an adaptive current control method for Hybrid Active Power Filter (HAPF). It consists of a fuzzy-neural controller, identification and prediction model and cost function. The fuzzy-neural controller parameters are adjusted according to the cost function minimum criteria. For this reason, the proposed control method has a capability on-line control clings to variation of the load harmonic currents. Compared to the single fuzzy logic control method, the proposed control method shows the advantages of better dynamic response, compensation error in steady-state is smaller, able to online control is better and harmonics cancelling is more effective. Simulation and experimental results have demonstrated the effectiveness of the proposed control method.

Keywords: hybrid active power filter (HAPF), fuzzy neural controller, reactive power compensation, predictive control, passive power filter, power quality
