Discrete-time integral control of thePWM DC-DC converters is considered using recentlydeveloped general sampled-data power stage models. Either the voltage or current of the power stage can be controlled.Both state feedback and output feedback are addressed.Line and load regulation are achieved through a discrete-time integrator.By adding an analog filter, the average value of output can be regulated.State observers are constructed for converters belonging to a certain class.
