The concept of decentralized finite-time stabilization for large-scale interconnected linear systems is introduced
by the definition of finite-time stability. The design of decentralized state feedback controllers and decentralized dynamic output feedback controllers is given for a class of large-scale interconnected linear systems. A sufficient condition is provided by using linear matrix inequality (LMI). When the feedback control laws are applied to the systems, the closed-loop systems are finite-time stable. A simulation example shows the feasibility and effectiveness of the conclusion.
