Delay-Dependent State Estimation of Static Neural Networks with Time-Varying and Distributed Delays

Abstract EN

This paper focuses on studying the state estimation problem of static neural networks with time-varying and distributed delays.

By constructing a suitable Lyapunov functional and employing twointegral inequalities, a sufficient condition is obtained under which the estimation error system is globally asymptotically stable.

It can be seen that this condition is dependent on the two kinds of time delays.

To reduce the conservatism of the derived result, Wirtinger inequality is employed to handle a cross term in the time-derivative of Lyapunov functional.

It is further shown that the design of the gain matrix of state estimator is transformed to finding a feasible solution of a linear matrix inequality, which is efficiently facilitated by available algorithms.

A numerical example is explored to demonstrate the effectiveness of the developed result.
