Decentralized control of an iner-connected electric energy system subject to information flow constraints

This paper considers the problem of designing a decentralized feedback controller for a class of interconnected linear dynamical systems. The structure of each local controller is constrained to be such that it can be defined via a constant output feedback matrix, and necessary conditions for the resulting parameter optimization problem are given in the form of simultaneous nonlinear algebraic equations. Two methods for solving these equations are discussed and compared relative to computational efficiency. The design methodology is then illustrated via an application to an interconnected electric energy system.
