A stabilizing model predictive controller for voltage regulation of a DC/DC converter

Using a nonlinear converter model, a numerical on-line optimization free model predictive control (MPC) is proposed for a converter to regulate the capacitor voltage. The MPC is given analytically by minimizing an energy function of the tracking error with its global exponential stability under input constraints. The outer-loop PI controller is adopted to eliminate an offset errors caused by a plant-model mismatch.
