    Considers two gas transmission stations at either end of the pipeline sited in areas of different population density, this would mean that different pressure constraints would be placed upon them. The solution currently used in the gas industry is to control the outlet pressure of the up stream station, to a value which could exceed 100 lbf/in2. The up stream pressure is modulated by a ...

    Describes research into the design of real-time synchronisation software for a high-speed packaging machine utilising independent drives. The machine is of a novel modular design which exploits the flexibility that is introduced by the use of software controlled independent drives. It is intended for use in flexible manufacturing applications in which large quantities of various products are produ... View full abstract»

  • Quality software

    Publication Year: 1989, Page(s):5/1 - 5/4
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (204 KB)

    Addresses the problem of developing quality software, specifically in industrial applications. Both the market needs and the motivation exist for higher quality software. After identifying these driving forces, an attempt is made to define software quality. The author goes on to discuss ways that the quality of software produced can be improved using contemporary methods. It is concluded that the ... View full abstract»

  • The role of CUTLASS in software reliability

    Publication Year: 1989, Page(s):1/1 - 1/3
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (132 KB)

    Describes the approach taken within the CEGB to control system software reliability in major control and instrumentation refurbishments in power stations. The CEGB has adopted a policy of using a real-time software system developed in-house to cater for computer control, plant monitoring and operator displays in power stations. This is known as CUTLASS (Computer User's Technical Language And Softw... View full abstract»

    Outlines the design of a microprocessor based controller with fault tolerance from transient disturbances. Such events can cause erroneous jumps within executing software. Fault tolerance is achieved through automatic enhancement of the application software. Performance issues are briefly discussed View full abstract»

    Describes the family of self-tuning PI controllers proposed for distribution within the Bristol Babcock range of programmable industrial controllers. The algorithms include a `one-shot' closed-loop cycling procedure, a pattern recognition adaptive strategy and a recursive least squares based scheme. The paper details those refinements appended to the basic algorithms to ensure reliable operation u... View full abstract»

    The author presents the methodology called RISCS (Reliability, Integrity and Safety Critical Studies) developed by CSE for assessing the safety and reliability of the computer-based control systems. The methodology permits differing hazards of the system to be assessed at differing levels, making use of the most powerful assessment techniques available. RISCS assesses the reliability, system integ... View full abstract»
