Abstract

A new approach is proposed for the design of a pulse width modulated (PWM) feedback control scheme regulating a full bridge buck converter (FBBC) in an output signal stabilization task. The approach is based on the specification of a dynamical feedback control law which accomplishes asymptotic stabilization to a preselected constant operating point, for the average PWM converter model. The approach emphasizes the use of the Fliess generalized observability canonical form (GOCF) of the average converter model and partial inversion techniques
