Simple switching signal design for H∞ performance and control of switched time-delay systems

In this paper, a simple switching signal design scheme for H∞ performance analysis and control of switched time-delay systems with linear fractional perturbations is developed. Delay-dependent LMI-based criteria are proposed to achieve the design of switching signal and control. All the LMI problems in our main results can be solved numerically by Matlab LMI toolbox. Wirtinger-based inequality is used in our approach to improve the conservativeness of the past research results. Finally, some numerical examples are illustrated to show the main improvement.
