In this paper, a class of recurrent neural networks with multi-proportional delays is studied. The non-linear transformation transforms a class of recurrent neural networks with multi-proportional delays into a class of recurrent neural networks with constant delays and time-varying coefficients. By constructing Lyapunov functional and establishing the delay differential inequality, several delay-dependent and delay-independent sufficient conditions are derived to ensure global exponential periodicity and stability of the system. And several examples and their simulations are given to illustrate the effectiveness of obtained results. (C) 2015 ISA. Published by Elsevier Ltd. All rights reserved.
