In this paper we use the parameter-dependent Lyapunov function framework de
veloped by Haddad and Bernstein to address the problem of robust stabilizat
ion for systems with parametric uncertainty and system delay. The principal
result involves the construction of a modified Riccati equation for charac
terizing a memoryless (delay-independent) feedback controller that guarante
es robust stability in the face of parametric uncertainty and time delay. (
