Abstract

In this paper a Model Predictive Control (MPC) for buck synchronous DC-DC converter has been designed. The proposed solution considers an off-line explicit MPC formulation resulting in a PieceWise Affine (PWA) controller structure. A model based observer for inductor current has been taken into account to overcome the several problems related to sensors in high current ripple DC converters. Reported numerical results show that the proposed control scheme enhances the overall performances of common averaged current mode control with linear regulators.
