Voltage Control Of DC-DC Buck Convertor Using Super-Twisting Sliding Mode Control

Abstract

Non-linear DC-DC converters are employed in any case where it is necessary to stabilize a supplied DC voltage to a specific value. This converter output voltage alone typically oscillates, has significant overshoot, and takes a long time to stabilize. Additionally, when the supply voltage and load vary, it cannot provide the desired output voltage. Numerous controllers are needed to manage this issue and achieve continuous, stable output voltage and quick reaction. Due to their simplicity, FOPID controllers have typically been used with convertors to get the desired output voltage. However,the use of FOPID controllers in non linear systems does not satisfactory. In order to improve system efficiency, non-linear controls are necessary. In this study to provide quick and reliable buck converter efficiency, a super twisting sliding mode controller based on the super-twisting algorithm has been developed
