Decentralized H/sub /spl infin// control for interconnected large-scale systems

The problem of decentralized H/sub /spl infin// control for interconnected large-scale systems is considered, and a complete design approach for a local state-feedback decentralized H/sub /spl infin// controller is proposed. The solution for local controllers is carried out merely by iteratively solving a set of local algebraic Riccati equations. Finally, the effectiveness of the approach is verified by a simulation example.
