英文摘要： The subject focuses on the estimation of the wireless sensor network with multiplicative noise, time delay and packet loss. Firstly, the mathematical model of the wireless sensor network with multiplicative noise and packet loss which is also termed as multiplicative-wireless-sensor-network and the mathematical model of multiplicative-wireless-sensor-network with time delay are established. Based on the above models, the optimal estimator and the corresponding information fusion estimator for the wireless sensor network will be designed; Secondly, by considering some uncertainties in the model based on the above theory and results,the robust optimal estimators of the multiplicative-wireless-sensor -network and the delayed multiplicative-wireless-sensor-network will be designed. At the same time, for the uncertainties of the statistical characteristics of the noises, the H-infinity estimator of the multiplicative-wireless-sensor-network will be designed, and the convergence of all the above estimators will be analyzed; Finally, the results of the above theory will be simulated, and the experiments and the application will be made on the mobile robot. The research of this subject can not only preliminarily establish the estimation theory of the wireless sensor network with multiplicative noise, further develop t
