DESIGN OF STABILIZABLE CONTROLLERS FOR LARGE SCALE SYSTEMS USING AGGREGATION TECHNIQUES.

The aim of this paper is to develop a methodology for the design of controllers insuring the stability of large scale systems using aggregation techniques. Development of reduced order model and structure of the aggregation matrix are investigated and discussed. Conditions are obtained to guarantee the stability of the initial system model using controllers based on the reduced models. Then methodology for the design of stabilizable controllers is developed insuring the optimality and stability of the initial system model. Finally the developed methodology is applied to a case study and the results are reported and discussed.
