Fuzzy-model-based H∞ control for discrete-time switched systems with quantized feedback and unreliable links

This paper addresses the issue of fuzzy-model-based H∞ control for discrete-time switched systems with quantized feedback and unreliable communication links. It is assumed that packet dropouts and quantized feedback exist simultaneously in the unreliable links of fuzzy switched systems. By constructing a suitable Lyapunov-Krasovskii functional together with an improved Jensen inequality and refined reciprocally convex matrix inequality, a new set of sufficient conditions are established. Finally, the applicability and effectiveness of the derived approaches are illustrated through a numerical example.
