Abstract :
Feedback stabilization of the nominal periodic operating condition of PWM DC-DC converters is considered, using recently developed general sampled-data models. Two types of discrete-time washout filter aided feedback stabilization scheme are proposed and studied in detail. These are voltage reference compensation and dynamic ramp compensation. The stabilization schemes preserve the nominal periodic operating condition through washout filters as the system parameters vary
