Adaptive and Robust Stabilization of Flyback Power Converters with Digital Control

DC to DC power converters are electrical system used to adapt an input voltage source to an output load which may change with unknown variations but bounded. We propose an observer-based control strategy with global asymptotic stability property that uses a parameter estimate to compensate input sources and output load variations. The demonstrator of this control strategy is done with a 30W Flyback Converter. This paper shows a physical real time implementation of the control algorithm using C2000-familly processor from Texas Instrument.
