Hinfinity Tracking Observer-Based Control of the Buck Power Converters

Abstract : In this paper, an H8 robust observer based control is proposed for guaranteeing tracking performances of closed loop nonlinear systems. This approach is used to controlling DC-to-DC switched power converters of Buck type. The results are given in terms of linear matrix inequalities and they guarantee global asymptotic stability of the tracking error. The design conditions obtained using Lyapunov approach are given in terms of solvability as a set of Linear Matrix Inequities (LMIs) terms.
