Abstract

In this paper, the sampled measurement is used to estimate the neuron states, instead of
the continuous measurement, and a sampled-data estimator is constructed. Leakage delay is used to
unstable the neuron states. It is a challenging task to develop delay dependent condition to estimate
the unstable neuron states through available sampled output measurements such that the error-state
system is globally asymptotically stable. By constructing Lyapunov–Krasovskii functional (LKF), a
sufficient condition depending on the sampling period is obtained in terms of linear matrix inequalities
(LMIs). Moreover, by using the free-weighting matrices method, simple and efficient criterion
is derived in terms of LMIs for estimation
