Abstract

This paper describes a collaborative project involving British Gas plc, Midlands Research Station, Solihull, the Control Theory & Applications Centre of Coventry University, the Energy Technology Support Unit, Harwell and Eurotherm Controls Ltd, Worthing. The project is concerned with the design, development and real-time evaluation of a new bilinear self-tuning controller, which is primarily being aimed at improving temperature control of high temperature gas fired industrial heating plant. The largest energy savings are anticipated on plant experiencing variable operating conditions which may occur under continuous operation or during batch process changes. To provide for a realistic comparison, the performance of the bilinear self-tuner is compared to that achieved using a standard industrial auto-tuned PID controller when applied to an industrial test furnance.
