Abstract:This article presents a framework for annular finite‐time filtering problem for discrete‐time mean‐field stochastic systems with state‐ and disturbance‐dependent noise. Both static and dynamic event‐triggered mechanisms are introduced, which are related to two different thresholds and internal variables, respectively. Based on mean‐field theory and the Lyapunov functional method, two groups of sufficient conditions are derived to ensure the filtering error systems have annular finite‐time boundedness under an… Show more
