An alternative way to use Posicast to damp oscillations in lightly damped control systems is proposed in this paper. Specifically, it is suggested that the Posicast technique be used within a feedback system, instead of the classical feedforward configuration. There are many types of Posicast, but discussion and analysis are focused here on the classical "half-cycle" Posicast form. Theoretical analysis and a design example are used to compare classical Posicast and the proposed feedback control method. An experimental result from a power converter application is also presented.
