【Abstract】 A class of global robust stability problem in fuzzy neural network with parameter uncertainty and stochastic perturbation was investigated on the basis of investigation results of Takagi-Sugeno(TS) fuzzy system.Based on the Lyapunov’s stability theory and using stochastic analysis approach,a judgement criterion was set up for the globally robust stability of this system in terms of linear matrix inequalities and this criterion generalized the results given by the literatures available,exhibiting less conservative character.A numerical computation example verified the effectiveness of the result.更多还原
