Fractional-Order Vectorial Halanay-Type Inequalities With Applications for Stability and Synchronization Analyses
Peng Liu, Jun Wang, Zhigang Zeng · IEEE Transactions on Systems Man and Cybernetics Systems · 2022
The Halanay inequality is widely used in various time-delayed dynamical systems analyses and its vectorial form has become available recently. In this article, the integer-order vectorial Halanay-type inequality is further extended to fractional-order ones in both time-invariant and time-varying forms. It is shown that the fractional-order vectorial Halanay-type inequalities hold under the derived conditions in the form of$M$-matrices. In addition, the time-invariant inequalities are applied to analyzing the stability and synchronization of fractional-order systems with two numerical examples to substantiate the theoretical results.
