A control strategy for ethanol concentration in continuous sake fermentation was investigated. The fermentaiton system consisted of repeated fed-batch culture as a pre-fermentator and an immobilized yeast-packed reactor;these tanks were connected in series. It was not easy to control this system compared with a single-stage reactor, since the broth of the pre-fermentor in which the ethanol concentration was increased was fed to the reactor continuously, and this acted as a chronic disturbance. To solve this problem, an adaptive controller for the pre-fermentor and a fuzzy controller fot the reactor using a mathematical model were constructed. Additionally, a leaning control system, was prepard to estimate the maximum specific growth rate which was difficult to identify by adaptive control;fuzzy theory was applied to the learning system.
