This manuscript analyzed the delay-dependent stability problem for non-linear switched singular time-delay systems based on average dwell time and delay decomposition approach. Both cases of time-delays namely constant and time-varying delays are treated in the switched singular systems. Based on piecewise Lyapunov-Krasovskii functional, linear matrix inequality technique and an average dwell time approach, sufficient conditions which ensures that the delay-dependent exponential stability conditions for uncertain switched singular systems are discussed. Finally, numerical examples and simulations are provided to demonstrate the effectiveness of the proposed techniques. © 2014 Wiley Periodicals, Inc.
