HARMONIC REDUCTION IN HIGH FREQUENCY (400HZ) AIRCRAFT POWER SYSTEM APPLYING ARTIFICIAL INTELLIGENCE TECHNIQUES IN SHUNT ACTIVE POWER FILTER

A novel ANN controlled shunt filter designed for aircraft power system has been proposed in this paper. The conventional shunt Active Power Filter (APF) model has been improved using Genetic Algorithm and Fuzzy Logic tools. Genetic Algorithm has been used to determine the optimum value of filter inductor; whereas Fuzzy Logic controller has been used in voltage control loop of the filter. The improvement in the control scheme using ANN control makes APF versatile for compensation of reactive power, harmonic currents, and unbalance in source voltage. Proposed aircraft shunt filter also provides proper solution to the neural current in the system. The simulated results clearly bring out the effectiveness of the proposed control method of aircraft shunt APF.
