    The Dryer section of New Thames paper machine incorporated over 400 bearings, the failure of any one of these will shut the machine and incur penalties due to lost production of many thousands of pounds. It is therefore essential, if profitability is to be maximized, that bearing defects are identified so that scheduled replacement is possible and production is not disrupted. The most widely used ...

  • Monitoring and diagnostics using state estimation and artificial intelligence

    Publication Year: 1990, Page(s):8/1 - 8/3
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (124 KB)

    Condition monitoring and diagnostics require detailed information about the performance of the plant so that clues giving an early warning of a failure or a set of failures are noted. State estimation and observer concepts are useful for extracting information from the plant. Artificial intelligence methods can use these information for processing and decision making. This work is concerned with m... View full abstract»

    Presents the results of some collaborative work carried between the Control Systems Centre (CSC) at Sunderland Polytechnic and the Sunderland and South Shields Water Company (SSSWCo.). The SSSWCo. supplies a large population in the North West of England using three types of raw water sources which include bore holes, reservoirs and river abstraction. Water abstracted from bore holes requires littl... View full abstract»

    Performance requirements in aeronautics and the rapid growth of electronics, especially of digital computers, have gradually led to the combination of advanced control theories and fly-by-wire technology. This has resulted in designs for which the control systems are flight critical. The required reliability is usually achieved by a multiplication of sensors, computers and actuators accompanied by...

  • Fault tolerant data acquisition and interpretation using expert shell driven monitoring systems

    Publication Year: 1990, Page(s):6/1 - 6/2
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (88 KB)

    Sophisticated computer based data acquisition and interpretation systems are potentially very powerful diagnostic tools for many condition monitoring applications. However, an automated system has to be able to cope with occasional bad data due to a variety of causes and still provide reliable results. This problem has been tackled by developing an expert shell driven system that incorporates the ... View full abstract»

    Describes a knowledge based approach to the health condition monitoring problem of a large complex system. The specific issues concerned include failure detection, isolation and identification of aircraft flight control systems. Few papers have substantially addressed the knowledge based approach for failure detection and diagnosis for aircraft flight control systems. The authors offer a novel app... View full abstract»

  • The cost effectiveness of expert systems for roadside electronics

    Publication Year: 1990, Page(s):7/1 - 7/4

    Roadside electronics are becoming widely used for providing economic distribution of broadband communication services. These usually consist of a cabinet at the side of a road taking in a trunk source and distributing services to a number of customers. Roadside electronics are used as one way of reducing per-customer cost by moving the launch point for services closer to their premises. They are a... View full abstract»

    Much effort has been expended in recent years on the development of fault detection and isolation (FDI) techniques for industrial plant. The increasing availability of localised computational power together with the richness of communication provided by digital bus technology offers the necessary infra-structure for FDI techniques to be applied in a more systematic manner throughout industry. The ... View full abstract»
