中文摘要： 本项目研究网络多因素综合影响下的动态系统基于有损信息的故障预报理论与算法。研究内容包括：网络环境中基于有损信息的非线性动态系统状态估计理论；网络环境中基于有损信息的动态系统多步故障预报理论；存在模型和噪声统计特性的不确定性，且处于复杂、变化环境中的网络化动态系统鲁棒故障预报算法等问题。本项目是申请人已经完成的国家自然科学基金项目复杂网络化控制系统的故障诊断与安全性（批准号：60874053，起止期：：2009.1-2011.12），网络化控制系统的故障诊断与容错控制（批准号60274014，起止期：2003.01-2005.12）研究工作的延续和扩展。通过完成本项研究，期望能够充分了解网络因素对网络化系统或者基于网络的远程故障预报算法产生的影响，提出和建立较为系统的网络化系统基于状态估计理论的多步故障预报、鲁棒多步故障预报算法等。

英文摘要： This project will research the fault prognostics theory and algorithm based on lossy measurements for dynamic systems under the combined impacts of multiple network induced factors. The proposed research works include the state estimation theory based on incomplete information for nonlinear dynamic system in network environment, multistep fault prognostics theory based on lossy measurements for networked dynamics systems, robust fault prognostics algorithm for networked dynamic system operating in complex and changing environment with uncertainty of noise statistical properties and systems model etc. These research thrusts are the continuation and extension of our finished projects Fault diagnosis and safety theory for complex networked control systems(Grant number 60874053，from 2009.1 to 2011.12) and Fault diagnosis and fault-tolerant control for networked control systems(Grant number 60274014; From 2003.01 to 2005.12), which are all sponsored by the National Natural Science Foundation of China. By completing this project, our goal is to fully understand the impacts of multiple network induced factors to networked system fault prognostics or remote fault prognostics over network, and develop new estimation theory based multistep fault prognostics theory and robust multistep fault prognostics theory for networked dynamic systems etc.
