Abstract:

This paper addresses quadratic stability guaranteed cost control for a class of linear discrete-time switched systems with uncertain multiple time-delays in state and input based on LMI theory. By using multiple Lyapunov functions and constructing linear matrix inequalities, several sufficient conditions for the problem under study is derived with a state-based switching law. Controllers of the subsystems are designed and the switching law obtained simultaneously. A numerical example shows effectiveness of the method.

Key words: switched systems, time-delays, stability, feedback, matrix inequality
