多时滞Hopfield神经网络的鲁棒稳定性及吸引域的估计

Robust stability of a class of Hopfield neural network model with parameter perturbations and multiple time-delay is analyzed by constructing a suitable Lyapunov functional and sector conditions.The sufficient condition for the asymptotic stability of equilibrium point is given.By the definition and properties of matrix norm,a corollary expressed in the form of norm is derived.An estimating method of the domain of attraction for equilibrium point is obtained.The simulation results have proved the effectiveness of the conclusions.
