Stability analysis for continuous-time genetic regulatory networks with delays

This paper analyzes the global exponential stability for the continuous-time genetic regulatory networks (GRNs) with delays. By constructing a new Lyapunov functional, a sufficient condition of the global exponential stability for a class of the continuous-time GRNs is given in the form of several elementary inequalities. This sufficient condition is weaker than one obtained in [Appl. Math. Comput., vol. 220, pp. 507-517, 2013]. Finally, a pair of numerical examples are provided to show the effectiveness of the proposed analysis approach.
