Feedback stabilization of the nominal periodic operating conditionof PWM DC-DC converters is considered, using recentlydeveloped general sampled-data models. Two types of discrete-time washout filter aided feedback stabilizationschemes are proposed and studied in detail. These arevoltage reference compensation anddynamic ramp compensation.The stabilizationschemes preservethe nominal periodic operating condition through washout filters as the systemparameters vary.
