This paper is directed at the problem of designing a set of stabilizing proportional-integral-derivative (PID) controllers for each decoupled subsystem of a multi-input multi-output system based on PID stabilization theorem [1]. It is well known that state interconnection terms of ith subsystem are arising out of N-interconnected subsystem dynamics can be treated as perturbation acting on that subsystem. An LMI optimization problem is formulated to ensure the stability of the composite system while the designed decentralized controllers are employed. A genetic algorithm based search technique is adopted to select an optimal PID controller gains from a designed search space of stabilizing controllers in order to have an optimum value of performance index. A linearized model of multi-machine infinite-bus system is considered for simulation to show the effectiveness of the design procedure.
