Finite-Time Sampled-Data Control for Networked Dynamic System

This paper studies the finite-time stability of the networked dynamic system under sampled-data control. By taking the interconnected structure into consideration and employing input-delay approach, tractable conditions that only depend on individual subsystem are proposed to ensure the finite-time stability of the networked dynamic system. By utilizing the Finsler's lemma, the existence conditions of the decentralized state feedback controller are derived. An example of interconnected seesaw-cart system is given to illustrate the effectiveness of the proposed method.
