In this paper, the problem of the E-exponential stability of linear switched singular systems composed of stable and unstable subsystems in discrete-time case is investigated. By using a multiple discontinuous Lyapunov function approach and exploring the properties of mode-dependent average dwell time(MDADT) switching signal, new sufficient conditions of E-exponential stability for linear switched singular systems are presented. Compared with the existing results, the proposed method is more flexible and tighter bounds on MDADT can be obtained. Finally, a numerical example is provided to illustrate the effectiveness of the proposed criteria.
