Robust guaranteed cost control for singular time-delay systems with saturation factors

We study the robust guaranteed cost control for nonlinear singular time-delay systems with saturation actuators. And our aim is to design a robust controller and a guaranteed cost controller. Some sufficient conditions on the existence of robust controller and guaranteed cost controller are obtained by using the linear matrix inequality approach (LMI). When these LMIs are feasible, the explicit expressions of robust controller and guaranteed cost controller are also obtained respectively.
