Decentralized controller design for a class of interconnected systems

Yuezu Lv, Qishao Wang, Zhisheng Duan
This paper considers the decentralized controller design for interconnected systems. For the case the interconnections
satisfy certain matching conditions, a decentralized static controller is presented, which is designed in a separate way. Based
on the presented controller, a relaxed sufficient condition is proposed, and corresponding decentralized static controller is also
given. Furthermore, decentralized dynamic controller is designed for interconnected systems with two subsystems satisfying the
relaxed sufficient condition. The efficiency of proposed controllers are demonstrated both theoretically and numerically.
