Abstract

In this article, the H∞ model reference problem in two degrees of freedom control methodology using dynamic output feedback for continuous-time linear systems is presented. The controller design is formulated in terms of Linear Matrix Inequalities (LMIs). An illustrative example is presented to demonstrate the utility of the proposed synthesis procedure.
