This paper is concerned with the problem of 𝜇 -stability of impulsive neural systems with unbounded time-varying delays and continuously distributed delays. Some 𝜇 -stability criteria are derived by using the Lyapunov-Krasovskii functional method. Those criteria are expressed in the form of linear matrix inequalities (LMIs), and they can easily be checked. A numerical example is provided to demonstrate the effectiveness of the obtained results.
