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.
