Control and Analysis of Pulse-Modulated Systems

The talk gives an overview of control and analysis problems associated with pulse-modulated systems. We focus specially on pulse-width modulated (PWM) systems and use the DC-DC converter as an illustrative example throughout the talk.

In the talk I present a number of different approaches which have been used to model pulse-modulated systems for different purposes. A discrete time model was used for stability analysis. A sampled data model was used for H-infinity control synthesis and the so-called dynamic phasor model was used for both stability and harmonic analysis pf PWM systems.
