Study on fuzzy gain-scheduled multiple mode predictive control of ALSTOM gasifier problem

Fuzzy modeling method has been shown to be useful to build multi-model of prediction control. But, in the case of real industrial process of ALSTOM gasifier problem, more complex problems must be considered such as multi-variable control problem and model accuracy problem, and so on. This paper presents fuzzy gain scheduled controller design followed by predictive Control (DMC). The combined use of the proposed method and DMC proves to be a suitable method to solve gasifier control problem. The good behaviour of this method and a comparison with usual PI control are illustrated on an industrial problem concerning gasifier control problem.
