Observer-Based Controller Design for Uncertain Large-Scale Systems with Time-Delays in Subsystem Interconnections

In this paper, the decentralized stabilization problem of uncertain large-scale systems with time-delays in subsystem interconnections is investigated.An observer-based controllers is developed using the Lyapunov method.For robust stability of the system, a sufficient condition is derived in terms of linear matrix inequalities (LMIs) which are solved by convex optimization algorithm.A numerical example is given to illustrate the proposed technique.
