Abstract
F uzzy logic has been applied to a batch microbial fermentation described by a model with two adjustable parameters which associate product formation with the increasing and/or stationary phases of cell growth. The fermentation is inhibited by its product and, beyond a critical concentration, also by the substrate. To mimic an industrial condition, Gaussian noise was added and the resulting performance was simulated by fuzzy estimation systems. Simple rules with a few membership functions were able to portray bioreactor performance and the feedback interactions between cell growth and the concentrations of substrate and product. Through careful choices of the membership functions and the fuzzy logic, accuracies better than previously reported for ideal fermentations could be obtained, suggesting the suitability of fuzzy estimations for on-line applications.
