Non-separation method-based robust finite-time synchronization of uncertain fractional-order quaternion-valued neural networks

作者：

Highlights：

• Inspired by Lemma 1 in [36], a new fractional differential inequality is derived by means of inequality techniques and reduction to absurdity.

• Without the participation of sign function, two kinds of finite-time control strategies are designed.

• Non-separation method is first employed to explore the robust F-TS for the uncertain F-OQ-VNNs.

• Easily-verified robust F-TS criteria are derived, and settling time is explicitly reckoned.
