Exponential stabilization for discrete-time time-delay systems with actuator saturation

This paper considers the exponential stabilization problem for discrete-time linear systems with time-varying delay and actuator saturation. Compared with the existing methods, the time-delay information is sufficiently utilized in this paper, and less conservative restriction conditions are explored, then the improved exponential stabilization conditions are obtained in terms of linear matrix inequalities (LMIs). To estimate a larger domain of attraction, the feasibility problems are transformed into optimization problems. Numerical example show that our proposed method is more effective in reducing the conservatism.
