The information epidemic dynamics is represented by a network Susceptible-Infected-Susceptible (SIS) model contaminated by both process and observation noises to describe a perturbed disease-like information diffusion process. To reconstruct the contaminated system states, we design an optimal filter which ensures minimized estimation errors in a quadratic sense. The state estimation is then utilized to develop the optimal controller, for which the optimality of the closed-loop system is guaranteed by a separation principle. The designed optimal filter and controller, together with the separation principle, form a complete solution for the optimal control of network information epidemics with stochastic perturbations. Such optimal-filtering-based control strategy is also generalizable to a wider range of networked nonlinear systems. In the numerical experiments on real network data, the effectiveness of the proposed optimal control is validated and confirmed.<\/jats:p>","DOI":"10.1515\/auto-2020-0096","type":"journal-article","created":{"date-parts":[[2021,2,25]],"date-time":"2021-02-25T11:45:36Z","timestamp":1614253536000},"page":"122-130","source":"Crossref","is-referenced-by-count":3,"title":["Optimal filtering and control of network information epidemics"],"prefix":"10.1515","volume":"69","author":[{"given":"Fangzhou","family":"Liu","sequence":"first","affiliation":[{"name":"Chair of Automatic Control Engineering (LSR), Department of Electrical and Computer Engineering , 9184 Technical University of Munich , Theresienstr. 90 , , Munich , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zengjie","family":"Zhang","sequence":"additional","affiliation":[{"name":"Chair of Automatic Control Engineering (LSR), Department of Electrical and Computer Engineering , 9184 Technical University of Munich , Theresienstr. 90 , , Munich , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Buss","sequence":"additional","affiliation":[{"name":"Chair of Automatic Control Engineering (LSR), Department of Electrical and Computer Engineering , 9184 Technical University of Munich , Theresienstr. 90 , , Munich , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","published-online":{"date-parts":[[2021,1,30]]},"reference":[{"key":"2024072608413048704_j_auto-2020-0096_ref_001_w2aab3b7d500b1b6b1ab2b1b1Aa","doi-asserted-by":"crossref","unstructured":"W.
