T1 Guaranteed Estimation of Nonstationary Parameters of Difference Equations under Uncertainty JF Journal of Automation and Information Sciences JO JAI(S) YR 2018 FD 2019-03-01 VO 50 IS 11 SP 1 OP 18 K1 difference nonlinear equations K1 additive noise K1 nonstationary parameters K1 building optimal and guaranteed estimations K1 Bellman functions and Kalman–Bussi filter K1 numerical experiments AB The algorithms of building optimal and guaranteed estimations of nonstationary parameters of difference nonlinear equations with additive noise are given. The approaches to construct optimal estimations based on Bellman functions and Kalman–Bussi filter are presented. The results of numerical experiments for the problem of building guaranteed and optimal estimates for mathematical model of spreading one type of information are considered. The offered approach except theoretical interest has an important practical meaning. PB Begell House LK https://www.dl.begellhouse.com/journals/2b6239406278e43e,7d9ac7c524305052,22c94ca37fd1f98a.html
