Performance evaluation of closed loop controlled shunt active filter systems with different controllers

Abstract

In this paper, improving the dynamic performance of three phase closed loop controlled shunt active filter (SAF) is connected with different controllers Like PI, PR, FOPID and Fuzzy-logic controller. The SAF is executed with Voltage-Source-Inverter (VSI) & the switching-pulses are created utilizing assorted controllers. In this paper open loop three phase system with source disturbance and closed loop controlled SAF with different controllers are simulated. The simulation outcomes are presented to discover the outcome of SAF utilizing PI, PR, FOPID & FL controller are evaluated & the corresponding time-domain-parameters like rise time, settling time, peak time, steady state error are represented. THD is also compared with different controllers. The results showed that Fuzzy Controller system is the only controller has a better response than other controlled system.
