In particular, a new VSC design method based on Lyapunov-Metzler (LM) inequalities and the properties of strictly positive real (SPR) systems is suggested. The method is applied to the control of a dc-dc power converter: The performance of the resulting control system is superior to that afforded by a recently proposed alternative sliding-mode control technique. The definition of LM-SPR systems and its direct application to establish a procedure for designing the switching rule and VSC input are presented.3505-3513engDC-DC converterslinear matrix inequalities (LMIs)Lyapunov-Metzler (LM) inequalitiesstrictly positive real (SPR) systemsswitched systemsvariable-structure controlArtigo10.1109/TIE.2009.2026381WOS:000268896000026Acesso restrito875516058014262650620873805714620000-0002-1072-3814
