Stabilization of Large-Scale Interconnected Systems by Decentralized Dynamic Controllers

Abstract

This paper considers a decentralized stabilization problem for large-scale inter- connected systems. Dynamic controllers for subsystems are designed sequentially using the proper-stable-factorization approach. Sufficient conditions for simultaneous stabilization of the overall system as well as subsystems are obtained. It is also shown that the closed-loop overall system can be further made connectively stable under appropriate minimum phase conditions.
