    Concerns the implementation of the GPC self-tuning control on the excitation system of a turbo generator, taking into account several potential problems. The plant signals used for feedback are far from perfect. Although, robustness has received some consideration in self-tuning field, techniques most suitable for the control of excitation problem had to be identified and chosen for implementation...

  • Minimal controller synthesis for time-delay systems using a Smith predictor

    Publication Year: 1996, Page(s):4/1 - 4/5

    Minimal controller synthesis (MCS), an extension of MRACS, cannot readily be applied to time-delay systems. The article shows its application to such a system, a steam/water heat exchanger, by use of a Smith predictor. The MCS structure used is robust to parameter variations and disturbances View full abstract»

  • Disturbance attenuation in a hot strip rolling mill via feedforward adaptive control

    Publication Year: 1996, Page(s):1/1 - 1/4

    Adaptive techniques are relatively common on modern rolling mills; most are aimed at improving overall means and are not well suited to dealing with individual disturbances. The disturbance issue is addressed in this paper by a feedforward control scheme which has yielded performance benefits on an operational mill View full abstract»

  • Adaptive inferential control

    Despite the successful application of advanced predictive control algorithms to many industrial chemical processes satisfactory system performance cannot always be guaranteed. This is often the case where the infrequent measurement of key process outputs is unavoidable due to sampling limitations. In such situations the ability to detect deviations from desired process behaviour is significantly i... View full abstract»

  • A framework for the implementation of self-tuning/adaptive control at potable water treatment works

    Publication Year: 1996, Page(s):7/1 - 7/6

    This paper concerns the development of an interactive control scheme that applies self-tuning/adaptive control of simple PI and predictive PI controllers. There has been extensive interest in feedback control systems that automatically adjust their controller settings to compensate for changes in the process or the environment. Such systems are referred to as adaptive. The scheme described satisfi... View full abstract»

    The purpose of this paper is to address the issue of tuning the adaptation gains of MRAC systems using fuzzy logic technique to result in a fuzzy logic model reference adaptive control (FLMRAC) systems. The technique is implemented and applied to control a vehicle suspension system under severe operating conditions. Results show both good ride and handling performance as required in vehicles View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (400 KB)

    This paper details the findings of a comparative study when a single-input single-output bilinear self-tuning controller, which has been developed by the Control Theory and Applications Centre of Coventry University, is applied to a re-heat furnace at British Steel, Swinden Technology Centre, Moorgate, Rotherham. The performance of the bilinear self-tuner is compared to that of an industry standar... View full abstract»

  • Genetic-based pole-placement for self-tuning PID

    Publication Year: 1996, Page(s):3/1 - 3/3
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (184 KB)

    The design of pole-assignment self-tuning adaptive control is far from straightforward; the proper placement of poles is mostly done on a trial and error basis at least in the Z-domain. In this paper, a design scheme based on genetic algorithms is proposed. Genetic algorithms are used to find pole-locations globally over the unit circle View full abstract»
