<i>H</i>∞ performance analysis and switching control design for uncertain discrete switched time-delay systems

Abstract

The H∞ performance analysis and switching control of uncertain discrete switched time-delay systems with linear fractional perturbations are studied in this paper. The design of a simple switching signal is developed to acquire LMI conditions which achieve H∞ performance and switching control of discrete switched time-delay system. The conservativeness of obtained results can be improved by using the delay-partitioning approach. The using LMI variables number is less than our past proposed non-negative inequality approach. Finally, we use some numerical examples to illustrate the major improvement of the developed results.
