  • Knowledge-based approach to signal smoothing

    Publication Year: 1992, Page(s):23 - 28
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (448 KB)

    The task of signal smoothing is addressed as a special case of signal processing. Despite the fact that the smoothing methods are based on the analytic signal description and work on the quantitative representation of signals, good choice of a method is far from trivial and is based on the qualitative knowledge about the signal and noise. The authors aim is to help the usage of so called order sta... View full abstract»

  • A constraint maintenance system for the distributed resource allocation problem

    Publication Year: 1992, Page(s):197 - 202
    Cited by:  Papers (5)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (504 KB)

    The problem of allocating resources to activities may be decomposed into sub-problems, and these sub-problems may in turn be distributed across a society of problem solving agents. Distribution may be due to the geographical nature of the problem, or may reflect the structure of the organisation within which the activities take place. However, one might anticipate some degree of coupling between s... View full abstract»

    Publication Year: 1992, Page(s):165 - 170
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (244 KB)

    The paper explains a scheme for monitoring and diagnosing a plant in real time. This approach is based on application of system theory and artificial intelligence. System theory assists in obtaining information from the plant. This is done by constructing a mathematical model of plant. Comparing outputs from the real plant and its model provides useful information concerning the state of the syste... View full abstract»

  • Qualitative modelling of dynamical systems for on-line diagnosis-knowledge acquisition vs. structured modelling

    Publication Year: 1992, Page(s):153 - 158
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (320 KB)

    The paper concerns the problem of finding qualitative models for a given dynamical system. It is shown that the principal modelling steps that are used in well-known modelling and identification methods in control theory can also be applied to qualitative modelling. This provides a systematic framework to find qualitative or even mixed quantitative-qualitative descriptions of dynamical systems View full abstract»

  • An on-line intelligent control scheme for tension control

    Publication Year: 1992, Page(s):244 - 249
    Cited by:  Patents (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (352 KB)

    In a high speed process control environment, system dynamics (including the disturbance) are often non-linear and fast changing. The classical self-tuning control (STC) strategy takes several seconds before obtaining a system model, STC cannot thus handle a fast changing environment. Rule based control can compensate for fast changes, but lacks a formal method to optimise the controller's effort. ... View full abstract»

  • A novel approach to finite automata with control application to transport systems

    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (280 KB)

    The paper shows that finite automata are much closer related to discrete-time systems than assumed in the past. To this end a novel representation of Boolean functions is introduced similar to some sense to the canonical form of Shegalkin polynomials (1928). However common algebra is used instead of Boolean algebra. As a special class, systems which are linear in the sense of common algebra are co... View full abstract»

    A validation scheme has been developed to process aircraft flight data by coupling numerical and symbolic processing techniques. Feature interpretation and qualitative modelling approaches have been adopted since the observed, aircraft sensor network lacked instrumentation redundancy. The development of this application is presented in the context of a generic data reduction hierarchy for which im... View full abstract»
