Finite-time extended dissipative control for fuzzy systems with nonlinear perturbations via sampled-data and quantized controller

摘要

This paper investigates the problem of finite-time extended dissipative control for T-S fuzzy time-varying delay systems with nonlinear perturbations via sampled-data and quantized controller. The definition of finite-time bounded mixed extended dissipative of fuzzy systems is first proposed. Based on the constructed Lyapunov-Krasovskii functional(LKF) and Peng-Parks integral inequality, some sufficient conditions are obtained in the form of linear matrix inequalities(LMIs), which are less conservative than other papers. By combining the input delay approach and dynamic quantizer, the sampled-data and quantized controller is designed to guarantee that the T-S fuzzy system is finite-time bounded mixed extended dissipative. Finally, some numerical examples and practical examples are presented to verify the feasibility and effectiveness of the proposed methods. (C) 2019 ISA. Published by Elsevier Ltd. All rights reserved.
