Comparison of Information Structures in Decentralized Dynamic Systems

This paper deals with the optimization problems we face when operating and designing a decentralized dynamic system. The system is controlled by a set of controllers—each having different information and control variables. Data acquisition and communication mechanisms of the controllers are specified by the information structure, which plays a very important role in the system performance. Through the study of a class of linear-quadratic regulator problems, we have demonstrated the relation of the merit of a structure versus its complexity, and have discussed various concepts in designing an efficient system.
