Adaptive finite-time passivity and synchronization of coupled fractional-order memristive neural networks with multi-state couplings

In this article, the adaptive finite -time passivity (FTP) and finite -time synchronization (FTS) of coupled fractional -order memristive neural networks with multi -state couplings (CFMNNMCs) are investigated. Firstly, a sufficient condition for guaranteeing the FTP of CFMNNMCs is obtained by developing an edge -based adaptive strategy and a state -feedback controller. Furthermore, a node -based adaptive controller is designed to ensure the FTP of CFMNNMCs. Additionally, with the help of properties of Gamma function and some inequality techniques, the adaptive FTS problem for the considered network model is addressed. Finally, two numerical examples are given to demonstrate the validity of the adaptive FTP and FTS criteria.
