Robust Voltage Control for the DC/DC Buck-Boost Power Electronic Converter

Abstract

This paper solves the voltage tracking of the DC/DC Buck-Boost power electronic converter via a robust direct control. The control design is based on an alternative model of the Buck-Boost converter and contains only voltage terms, thus achieving direct manipulation. The control performance is verified on a converter circuit built in the SimPowerSystem toolbox of Matlab-Simulink. The results show a good voltage tracking against parametric disturbances, as well as the viability of the experimental implementation of the control in a prototype.
