Armature Regulation of DC Motor using PI Controlled DC-DC Flyback Converter
Subject area: Science,Engineering and Technology · Area of research: Power Electronics
Abstract
Electricity supply obtained from DC sources like photovoltaic cells is not usually compatible with nominal bias voltage requirement for most appliances, hence the need for voltage conversion. One of such converter is the flyback converter system. The flyback converter is a DC-DC converter capable of stepping up or stepping down DC voltage while providing galvanic isolation between its input and output sides. In this work, a flyback converter system is designedusing the Amp and Volts seconds balance equations on the state space model. The designed system deployed a PI controller having gains obtained from classical root locus technique implemented in MATLAB SISOTOOL. The flyback converter circuit design considered a strategy that handles undesirable surge current during switching transitions so as to protect the circuit. It was demonstrated that by keeping the armature voltage constant, the DC Motor will run at constant speed even when acted upon by a variable load provided the load is not beyond the capacity of the motor. Also varying the armature voltage will ensure that DC motor runs at variable speed. The step response analysis of the closed loop controlled system shows that a rise time of 0.7ms and a peak overshoot of 5.11% were achieved giving the system a faster and stable response.
