Brief Paper: Improved exponential stability criteria and stabilisation of T-S model-based neutral systems

摘要

This study deals with the b-exponential stability and stabilisation problems for a class of T-S model-based neutral systems.To solve these problems, new Lyapunov¿Krasovskii functional candidates for this class of systems can be chosen by using the delay-decomposition approach and introducing some exponential functions into corresponding integrands. b-exponential stability conditions of the T¿S model-based neutral systems are established by using the Lyapunov¿Krasovskii functional and a modification integral inequality. An LMI-based state feedback controller design strategy for this class of systems is proposed based on one of the b-exponential stability conditions. Two numerical examples are also provided to illustrate the effectiveness of the proposed approach.
