Performance Comparison of Sampled Hysteresis and Predictive Control Methods for Tracking Current in APF

摘要

This paper presents a performance comparison of sampled hysteresis current control and predictive current control techniques during dynamic operating conditions in voltage source inverter (VSI) based applications. Mathematical analysis of both the methods are presented for current control application for tracking non-sinusoidal current. In particular, active power filter (APF) has been used for compensating reactive and harmonic component of load current. The performance of the current control techniques are compared for shunt current tracking of the APF based on the THD of the grid current and reference current tracking response time. The simulation work is performed in the Matlab/Simulink environment.
