Abstract

The method of extended linearization is proposed for the systematic solution of sliding mode controller design in DC-to-DC power converters of the boost and the buck-boost types. A nonlinear sliding surface with suitable properties is synthesized on the basis of the extension of a linear design carried out on the average incremental model of the converter. The obtained feedback strategies lead to asymptotically stable sliding modes with remarkable self-scheduling properties. Simulation examples are presented for illustrative purposes
