\(\alpha \)-Exponential Stability of Impulsive Fractional-Order Complex-Valued Neural Networks with Time Delays

摘要

This paper investigates the global \(\alpha \)-exponential stability of impulsive fractional-order complex-valued neural networks with time delays. By constructing proper Lyapunov–Krasovskii functional and employing fractional-order complex-valued differential inequality, some sufficient conditions are obtained to ensure the existence, uniqueness and global \(\alpha \)-exponential stability of the equilibrium point for the considered neural networks. Moreover, the exponential convergence rate is estimated, which depends on the parameters and the order of differentiation of system. Finally, one numerical example with simulations is given to illustrate the effectiveness of the obtained results.
