    The analysis and design of an intelligent control system, based on the fuzzy set theory and the well known PID control principle, are carried out. The structures of fuzzy PID controllers are built up utilising expert heuristics to perform PID control actions. The properties of such controllers are investigated in terms of their nonlinear equivalence, stability analysis and robustness examination. ... View full abstract»

    The long lead time for jig and fixture design is a serious bottle-neck in modern manufacturing. Efforts to automate the fixture design process using intelligent CAD systems have not been taken beyond the prototype stage, mainly because of impediments which include the requirement of complex data structures to represent the workpiece and its attributes. Two deficiencies in existing systems for fixt... View full abstract»

    In this paper, an efficient model-based diagnostic process is described for systems whose components possess a causal relation between their inputs and their outputs. In this diagnostic process, a set of focuses on likely broken components is first determined. Secondly, for each focus, the most informative probing point within the focus can be determined. Both these steps have a worst-case time co... View full abstract»

    Better automation is a key to the improvement of industrial competitiveness. However, in most industrial plants, full automation is not possible because intelligent decisions play an essential part in guaranteeing the success of the production process. The currently favoured solution is to rely on human controllers for intelligent input, although instances of installations with AI-based control do... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (842 KB)

    The basic idea of model-based diagnosis is to exploit knowledge about the structure and behaviour of the physical system to be diagnosed in order to identify diagnoses from discrepancies between observed and predicted behaviour. The authors describe the application of model-based diagnosis to the problem of fault localisation in power transmission networks. They also show that the resulting system... View full abstract»

    Compares fuzzy and Kalman-filter control systems for real-time target tracking. Both systems performed well in the presence of additive measurement noise. In the presence of mild process (unmodelled-effects) noise, the fuzzy system exhibited finer control. The authors tested the robustness of the fuzzy controller by removing random subsets of fuzzy associations or 'rules', and by adding destructiv... View full abstract»

    Failure mode and effects analysis (FMEA) is a design analysis procedure involving the investigation and assessment of the effects of all possible failure modes on a system. This kind of analysis is of growing importance in the automotive, aerospace and other advanced manufacturing industries, where increasingly complex electrical, electronic and mechanical systems are being combined in safety-crit...

    The paper describes the work of the TIGER ESPRIT Project in performing real-time situation assessment of dynamic systems. The goal of TIGER is to monitor a complex dynamic system in real time and make an assessment of whether it is working properly. If it is not working properly, it is desirable to identify the cause of the problem either from a set of known faults or to characterise an unknown fa... View full abstract»

    As the deployment of expert systems has spread into more complex and sophisticated environments, so inherent technological limitations have been observed. As a technique for overcoming this complexity barrier, researchers have started to build systems composed of multiple co-operating components. These systems fall into two distinct categories; those that solve a particular problem, such as speech... View full abstract»
