摘要
In this paper, the exponential stability problem is investigated for a class of discrete-time singular switched systems with time-varying delay. By using a new Lyapunov functional and average dwell time scheme, a delay-dependent sufficient condition is established in terms of linear matrix inequalities for the considered system to be regular, causal, and exponentially stable. Different from the existing results, in the considered systems the corresponding singular matrices do not need to have the same rank. A numerical example is given to demonstrate the effectiveness of the proposed result.
