Abstract

The robust delay-dependent H"~ control for an uncertain switched system with sampled-data input is investigated in this paper. The design of the sampled-data state feedback control technique is based on a computer digital control theory and used instead of analog elements. Hence designing a practical and useful feedback control strategy is a very important work in implementation. The time-varying delay approach is used to deal the sampled-data state feedback input problem. The upper bound for the sampled time of state is estimated from the proposed LMI optimization approach. A numerical example is illustrated to show the use of the main results.
