Comparison of Control Strategies using Soft Computing Techniques for Shunt Active Power Filters in Aircraft Power Utility of 400 Hz

Abstract

Three different control strategies for extracting reference currents for shunt active power filters optimized using adaptive tabu search and genetic algorithm have been compared and their performance has been evaluated under different load conditions. The compensation ability of different control strategies will be compared and suggestion will be given for optimum strategy to be used under different loads. Simulation results using MATLAB have been included.
