The state feedback results extend previous results on Quadratic Guaranteed Cost control to the case of uncertain time-delay systems. This is done by our definition of quadratic stability for uncertain time-delay systems with norm bounded uncertainty. It is shown that the state feedback controller can be constructed via solution of a parameter dependent Riccati equation.6en19950029511079
