Decentralized Finite-Time H ∞ Connective Control for a Class of Large-Scale Systems with Different Structural Forms

الملخص EN

Decentralized finite-time H ∞ connective control problem for a class of large-scale interconnected systems is studied in this paper.

The research aims at two structural forms, namely, the interconnected structure and the one with expanding construction.

A new method is proposed to design a decentralized state feedback control law for a large-scale interconnected system so that the closed-loop system is finite-time H ∞ connectively bounded.

The sufficient conditions for the existence of such a decentralized control law are deduced by using LMI method.

Another method is presented for a large-scale interconnected system with expanding construction which can be used without changing the decentralized state feedback control law of the original system to design a controller for the newly added subsystem so that both the new subsystem and the resulting expanded system are finite-time H ∞ connectively bounded.

The feasibility and effectiveness of the proposed method are verified by some simulation results.
