Robust guaranteed cost H∞ control for time-delay singular systems with input saturation

In this paper, the problem of robust H-infinity guaranteed cost control for a class of time-delay singular systems with input saturation is investigated. A sufficient condition of H-infinity robust stabilization which satisfies guaranteed cost index is given for the systems by constructing a generalized Lyapunov function and taking LMI approach. A guaranteed cost function for the closed-loop systems has an upper bound irrespective of all admissible parameter uncertainties. Finally, an illustrative example is given to demonstrate the effectiveness of the proposed method.
