This paper considers the discrete-time state feedback non-fragile mixed LQR/H∞ control problem with controller uncertainty. It is assumed that the controller has a time-varying norm-bounded uncertainty. The controller solving the discrete-time non-fragile control problem is designed. Necessary and sufficient conditions for the existence of such a controller… (More)
