Robust \(H_\infty\) control of uncertain Markovian jump systems with time-delay. (English) Zbl 0983.93075
The authors consider a class of stochastic, uncertain linear state-delay dynamic systems. The time-varying uncertainties are modelled by sums of Markovian jump processes and real-valued functions representing time-varying parametric uncertainties. To obtain sufficient conditions on the existence of a robust stochastic stabilizing and \(\gamma\)-suboptimal \(H_\infty\) state feedback controller, the authors apply the Lyapunov functional approach. In the construction of a robust stochastically stabilizing \(H_\infty\) state feedback controller, the numerical solution of a set of coupled linear matrix inequalities is used.
