In this paper, we develop a descriptor approach to simultaneous H2/H
control design for a class of uncertain time-delay systems with Markovian jump parameters. The rationale behind this approach is to exhibit the delay-dependence dynamics in the design procedure. In the system under consideration, the delay factor is constant, the jumping parameters are modelled as a continuous-time, discrete-state Markov process and the uncertainties are assumed to be real, time-varying and norm-bounded. A state-feedback control is derived for both the nominal and uncertain systems such that the H2-performance measure is minimized while guaranteeing a prescribed H
-norm bound on the controlled system. All the developed results are cast in the format of linear matrix inequalities (LMIs) and numerical examples are presented.
Keywords: simultaneous H2/H
control; time-delay systems; Markovian jump parameters; norm-bounded uncertainties.
