Abstract

This paper is concerned with control of the DC/DC boost converter. Specifically, we propose a solution for output voltage trajectory tracking. Because of the non-minimum phase property of this converter when voltage is the controlled output we design an indirect control strategy based on a combination of sliding modes and differential flatness. This means that we achieve output voltage trajectory tracking by means of a controller which is designed for output current trajectory tracking. We also present some experimental results using the proposed control strategy which show that satisfactory performance is achieved. We use the National Instruments TM PCI-6025E electronic card together with MATLAB®-Simulink®. Copyright © 2008 CEA.
