Event-based nonfragile state estimation for memristive recurrent neural networks with stochastic cyber-attacks and sensor saturations

Abstract

This paper addresses the issue of nonfragile state estimation (SE) for memristive recurrent neural networks (MRNNs) with proportional delay and sensor saturations. In practical engineering, numerous unnecessary signals are transmitted to the estimator through the networks, which increases the burden of communication bandwidth. In this paper, a dynamic event-triggered mechanism (DETM) is employed to select useful data instead of a static event-triggered mechanism. By constructing a meaningful LyapunovKrasovskii functional (LKF), a delay-dependent criterion is derived in terms of linear matrix inequalities (LMIs) for ensuring the global asymptotic stability of the augmented system. In the end, two numerical simulations are employed to illustrate the feasibility and validity of the proposed theoretical results.
