Quasi-projective synchronization of stochastic complex-valued neural networks with time-varying delay and mismatched parameters

Abstract

This paper aims to study the issue of stochastic quasi-projective synchronization of complex-valued neural networks with time-varying delays in the case of the simultaneous existence of parameter mismatch and stochastic disturbance. Instead of separating the real and imaginary parts, by constructing a suitable controller, a quasi-projective synchronization criterion of two nonidentical systems is established by combining the complex version It’s formula with some inequality techniques in the framework of complex domain. Meanwhile, the bound of synchronization error is estimated. Some sufficient conditions for special cases are also presented. Finally, the effectiveness of the obtained results are verified by a numerical example.
