Decentralized control for large-scale systems making best use of interconnections

摘要

In this paper, a new method is proposed in order to consider advantages or interconnections. Firstly, the studied systems are considered centrally. By LMI approach, 'centralized controllers' and a block-diagonal solution of Riccati inequality can be solved simultaneously. Secondly, a new equivalent form is got by adding and subtracting the term of 'centralized controllers', whose interconnections are matched. At last, the decentralized controllers are designed by regular method.
