Abstract

This paper handles with the Hadamard and the Caputo-Hadamard fractional derivative and stability of related systems without and with delay. Firstly, the derivative inequalities are obtained, which is indispensable in applying the theorems derived in this paper. Then, for systems without delay, we get the stability results by using the Lyapunov direct method and for systems with delay, we explore two useful inequalities to verify the stability. Examples are presented with numerical simulations to illustrate the effectiveness of our results.

摘要

本文研究了哈达玛尔(Hadamard)和卡普托-哈达玛尔(Caputo-Hadamard)分数阶导数以及相关无时滞和有时滞系统的稳定性。首先,得到了导数不等式,这在应用本文推导的定理时是必不可少的。然后,对于无时滞系统,我们使用李雅普诺夫直接方法得到稳定性结果,对于有时滞系统,我们探索两个有用的不等式来验证稳定性。通过数值模拟给出例子来说明我们结果的有效性。
