摘要：
This paper considers the problems of stability for continuous-time positive nonlinear systems with delay via T-S fuzzy modeling. Based on quadratic copositive Lyapunov-Krasovskii functions (QCLKFs) a simple sufficient condition of stabilityis is obtained, which is independent of the delay. Then, the proposed stability conditions are improved via high order relaxations in the QCLKF and its time derivative which can further reduce the conservativeness. The obtained stability conditions are formulated as LMIs. Last, the advantages and effectiveness of the theoretical results are illustrated by numerical example.
