摘要

研究了具有分布时滞的分数阶系统的稳定性和镇定问题。首先，利用扫频技术和广义Kalman-Yakubovi co $$ \overset{\check{} }{\mathrm{c}} $$ -Popov （KYP）引理，提出了一种新的FOSDDs稳定性条件。其次，基于所提出的稳定性条件，导出了具有范数有界不确定性的不确定FOSDDs的鲁棒稳定性条件。第三，基于所提出的鲁棒稳定性条件，得到了具有范数有界不确定性的不确定FOSDDs的一种新的鲁棒稳定性条件。最后，通过数值算例验证了所提结果的有效性。通过数值算例，将所提结果与已有的FOSDDs结果进行了比较，结果表明所提结果具有较小的保守性。

Stability Analysis and Stabilization of Fractional-Order Systems With Distributed Delay

This paper investigates the stability and stabilization problems of fractional-order systems with distributed delays (FOSDDs). Firstly, with the frequency sweeping technique and generalized Kalman-Yakubovi $\overset{ˇ}{c}$ -Popov (KYP) lemma, a novel stability condition for FOSDDs is proposed. Secondly, based on the proposed stability condition, a robust stability condition for the uncertain FOSDDs with norm-bounded uncertainties is derived. Thirdly, based on the proposed robust stability condition, a novel stabilization condition for the uncertain FOSDDs with norm-bounded uncertainties is obtained. Finally, several numerical examples are provided to show the effectiveness of the proposed results. Moreover, in the numerical examples, the comparison of the proposed results with the existing results for FOSDDs is shown to demonstrate that the obtained results are less conservative.

期刊介绍： Papers that do not include an element of robust or nonlinear control and estimation theory will not be considered by the journal, and all papers will be expected to include significant novel content. The focus of the journal is on model based control design approaches rather than heuristic or rule based methods. Papers on neural networks will have to be of exceptional novelty to be considered for the journal.
