✦ Synopsis

An adaptive feedback regulation scheme is proposed for the stabilization of average models of dc-to-dc power converters exhibiting unknown but constant resistive loads. The scheme is based on a dynamical feedback policy which suitably modifies the total energy of the closed-loop system while inducing appropriate damping injections on the desired stabilization error dynamics. The performance of the proposed adaptative regulators is tested through computer simulations including stochastic perturbation inputs.

Dynamical adaptive regulation of pulse-width-modulation (PWM) controlled power supplies is proposed using a suitable combination of average dynamical input-output linearization and the 'backstepping' controller design method. Nonlinear average models of dc to dc power supplies are not transformable
