This paper investigates the closed-loop fault detection problem for networked flight control system with asynchronous switching. Firstly, the original flight dynamics is modelled as a linear switched system including multiple operating points. Secondly, observer-based fault detection filters and robust tracking controllers are designed synergistically to detect faults and make the system track a given...
This paper focuses on monitoring and diagnosis problems to the antenna system in mobile communication network. Based on network management measurement report (MR) data, traffic statistics, frequency scan data and basic engineering parameters, the fault of antenna system in network could be found through noise filtering algorithm, inter-modulation interference analysis algorithm, correlation algorithm,...
Systematic error resulted from the pre-travel of the touch trigger probe is non-ignorable consititutent of inspection errors for On-Machine Measurennet (OMM). Based on analyzing the working procedure of probe, the mechanics condition of triggering mechanism under working situation is performed. Utilizing the results, a probe pre-travel mathematical model is established, which can describe the pre-travel...
A common objective in simulation is enhanced understanding of a system; an opened model which can be storage, retrieval, sharing, and invocation in a distributed environment and among Web-based component applications is essential for this objective. As the development of Internet and WWW, the actions in the WWW are not only the human-machine interaction, but also Semantic Web-based machine -machine...
