Abstract: | The robust stability and robust stabilization problems for discrete singular systems with interval time-varying delay and
linear fractional uncertainty are discussed. A new delay-dependent criterion is established for the nominal discrete singular
delay systems to be regular, causal and stable by employing the linear matrix inequality (LMI) approach. It is shown that
the newly proposed criterion can provide less conservative results than some existing ones. Then, with this criterion, the
problems of robust stability and robust stabilization for uncertain discrete singular delay systems are solved, and the delay-dependent
LMI conditions are obtained. Finally, numerical examples are given to illustrate the effectiveness of the proposed approach. |
