A Variable Sampling Frequency and Genetic Algorithm Fitted Predictive Controller for More Electric Aircraft Electrical Power System Shunt Active Power Filter

A five level H-bridge Shunt Active Power Filter that uses variable sampling frequency and a Genetic Algorithm fitted predictive control model to achieve excellent harmonic tracking with low device switching frequency, for More Electric Aircraft Electrical Power System (with a supply frequency in the range 360 Hz to 800 Hz) is proposed in this paper. The Predictive Control Shunt Active Power Filter is designed to track 5^th and 7^th harmonic current references up to 5600 Hz with nominal tracking errors less than ±2% while using a relatively low device switching frequency. The system is modelled and simulated in Matlab/Simulink and an analysis of the excellent tracking result using the Variable Sampling and Genetic Algorithm based model is provided.
