The uncertain systems under considered in this paper are subject to systems with norm-bounded time varying parametric uncertainty and a given quadratic cost function. Based on Lyapunov-Krasovskii functionals combining with LMI techniques the existence of guaranteed cost controllers is derived. Furthermore, the optimal guaranteed cost controller which minimizes the guaranteed cost of the closed loop uncertain system is introduced as well.
