| Abstract: | To deal with data dropouts and noise in data transmission, this paper studies robust guaranteed cost state estimation of discrete-time complex networks, and focuses on reducing influence of data dropouts and noises on state estimation. Using the Lyapunov stability theory combined with stochastic analysis, an existence condition of the gain matrix and the relevant design criteria used in the robust guaranteed cost state estimation are proposed with linear matrix inequalities. With convergence of the estimation mean-square error, the robust guaranteed cost performance requirements are satisfied. Numerical simulation shows effectiveness and applicability of the proposed design approach. |
| Keywords: | complex network noise data dropouts state estimation robust guaranteed cost control |
