Tunç, C.Mansız, K.2025-05-102025-05-1020232219-56882-s2.0-85181224775https://hdl.handle.net/20.500.14720/339This article deals with the problem of asymptotic stability of a fractional mathematical model as a nonlinear fractional differential system with a variable delay. Sufficient conditions of the asymptotic stability are obtained in relation to the system with a variable time delay using a suitable Lyapunov-Krasovskiǐ functional (LKF). The result of this article has new contributions to the existing ones in the literature. We also present an example as the numerical application of the result. © Palestine Polytechnic University-PPU 2023.eninfo:eu-repo/semantics/closedAccessAsymptotic StabilityLkfsNonlinear SystemsRiemann-Liouville FractionalArticle
