The focus of this paper is on the design of a decentralized state observer based decentralized guaranteed cost control for a class of large scale nonlinear interconnected systems whilst the nonlinear part is norm bounded.
Sufficient conditions for the asymptotic stability of the developed feedback control scheme are proposed in terms of linear matrix inequalities (LMIs) constraints, which can be efficiently solved by the LMI optimization techniques, to compute the control and the observation gains of the overall system, to maximize the domain of nonlinearity which leave the overall system stable and to minimize the upper bound of a given performance index. The efficiency of the proposed control approach is highlighted by numerical simulation dealing with the robust stabilization of a power system with three interconnected machines.
