# Variable-Structure Control of Power Electronic Converters

## Abstract

Interest in variable-structure control is justified by the necessity of robustly controlling systems whose structure switches between several configurations. Power electronic converters are such class of systems because they can be described by differential equations with discontinuous right-hand sides (i.e., discontinuous inputs). Moreover, they exhibit nonlinear behavior which can in some applications render unsuitable standard linear control approaches. Good control performance such as large bandwidth is ensured because the switching solution is obtained directly without any other form of supplementary modulation (PWM, sigma-delta modulation).
