Abstract :
This paper presents a new design procedure for a robust stability, robust Hinfin control and robust H2 control via dynamic output feedback for a class of uncertain linear systems. the uncertainties are norm bounded type. the state space matrices of the controllers are the solutions of some linear matrix inequalities problems. finally, these procedures are applied to an active radial magnetic bearing system to support a high-speed energy storage flywheel.
