Descripción
Sumario:This paper deals with the switching signal design to robust exponential stability for uncertain discrete-time switchedsystems with interval time-varying delay. The lower and upper bounds of the time-varying delay are assumed to beknown. By construction of a new Lyapunov-Krasovskii functional and employing linear matrix inequality, some novelsufficient conditions are proposed to guarantee the global exponential stability for such system with parametricperturbations by using a switching signal. In addition, some nonnegative inequalities are used to provide additionaldegrees of freedom and reduce the conservativeness of systems. Finally, some numerical examples are given toillustrate performance of the proposed design methods.
