Abstract
An algebraic Riccati equation approach to the non-fragile mixed LQR/H∞ control problem with controller uncertainty is presented. The corresponding controller is assumed to have time-varying norm-bounded uncertainties. Necessary and sufficient conditions of the existence of an admissible state feedback controller solving the non-fragile mixed LQR/H∞ control problem with controller uncertainly are given.
