Advanced control laws of DC–DC converters based on piecewise affine modelling. Application to a step-down converter

This study proposes two control techniques for a buck converter operating in continuous conduction mode at a fixed switching frequency. The non-linear behaviour of this switched system is represented by a discrete piecewise affine (PWA) model. The PWA representation offers a precise approximation of...
