An application of fuzzy modeling to distillation control

One of the recent trends in fuzzy control research is a shift from the use of fuzzy control rules to the utilization of fuzzy models for the design. In this study, modeling of a distillation column is investigated by applying a unique representation of the fuzzy model, which was proposed for the formulation of a simple fuzzy model tuning predictive controller (FMTPC) for MIMO systems in the author's (1994) recent paper. Through simulation studies, it is concluded that the proposed modeling method is adequate for the FMTPC, and its performance is satisfactory.
