LMI-based output feedback controller design-using a convex parametrization of full-order controllers

This paper proposes a unified output feedback controller synthesis method that employs LMI-represented specifications of H/sub 2/ norm control, H/sub /spl infin// norm control, root clustering and various multiobjective performances. For this purpose, we show a new parametrization of full-order controllers with a convex parameter set, and reduce synthesis problems to solving an LMI on the parameter space.
