Fuzzy Gain Scheduled Pi Controller for Resonant Power Converter Fed Hybrid Electric Vehicle with Bldc Motor Drive

Abstract: Over the years, it has seen the power conditioning move from simple, but extravagant linear regulators, through early low frequency pulse-width modulated systems, to high-frequency square wave converters, which pack the same power handling capabilities of earlier designs into a fraction of their size and weight. At present, a novel attack is upon us the resonant mode converter and while extending new benefits in performance, size and cost, this new technology brings with it an added dimension of complexity. The aim of this paper is to provide a system for manipulating the speed of a Brushless DC motor (BLDC) in a Hybrid-Electric Vehicle fed resonant mode inverter. Resonant inverter is used for DC-AC conversion with current resonance. The inverter used to regulate voltage and fed into the BLDC motor through a motor driver circuit. In this paper, the resonant inverter fed BLDC motor drive for hybrid-electric vehicle system simulated using An MATLAB/Simulink software tool. PI controller and Fuzzy Gain Scheduled PI controller are used for closed-loop control of the projected scheme.
