abstract

in this paper, we investigate the delay-dependent robust stability of fuzzy cohen-grossberg neural networks with markovian jumping parameter and mixed time varying delays by delay decomposition method. a new lyapunov-krasovskii functional (lkf) is constructed by nonuniformly dividing discrete delay interval into multiple subinterval, and choosing proper functionals with different weighting matrices corresponding to different subintervals in the lkfs. a new delay-dependent stability condition is derived with markovian jumping parameters by t-s fuzzy model. based on the linear matrix inequality (lmi) technique, maximum admissible upper bound (maub) for the discrete and distributed delays are calculated by the lmi toolbox in matlab. numerical examples are given to illustrate the effectiveness of the proposed method.

LMI approach for global robust stability of Cohen-Grossberg neural networks with multiple delays

In this paper, we investigate the global robust stability of the equilibrium point of a class of Cohen–Grossberg neural networks with multiple delays and uncertainties. The new criteria for the global robust stability are given by way of constructing a suitable Lyapunov functional. The criteria take the form of linear matrix inequality (LMI), and are independent of the amplification function. C...

New Conditions on Global Stability of Cohen-Grossberg Neural Networks

In this letter, we discuss the dynamics of the Cohen-Grossberg neural networks. We provide a new and relaxed set of sufficient conditions for the Cohen-Grossberg networks to be absolutely stable and exponentially stable globally. We also provide an estimate of the rate of convergence.

Periodic Oscillation of Fuzzy Cohen-Grossberg Neural Networks with Distributed Delay and Variable Coefficients

A class of fuzzy Cohen-Grossberg neural networks with distributed delay and variable coefficients is discussed. It is neither employing coincidence degree theory nor constructing Lyapunov functionals, instead, by applying matrix theory and inequality analysis, some sufficient conditions are obtained to ensure the existence, uniqueness, global attractivity and global exponential stability of the...
