Abstract

This paper proposes the application of a switched robust predictive control applied to output voltage control of a three-state switching cell boost converter considering the average space-state equivalent boost model. The proposed technique follows the switched quadratic performance index minimization principle modeled via linear matrix inequalities (LMIs) to closed-loop stabilization problem of a boost converter. The simulation results evidence the closed-loop stabilization of the presented converter using the switched predictive control demonstrated through the time response analysis and the closed-loop boundary ellipsoids procedure. This study demonstrated that the proposed control technique is suitable to output voltage control of boost converter. As future works are the validation test in the experimental setup.
