A predictive dead-beat PI current controller for active power filters

In this paper, a predictive dead-beat proportional-integral (PI) current control algorithm is studied for shunt active power filters (APFs). To investigate the effectiveness of the proposed control scheme a digital control based simulation model is built using commercially available VisSim software. Performance comparison with different control schemes are carried out. Excellent performance of active power filter has been achieved based on the proposed control strategy.
