This paper aims to determine the optimal substrate feeding that is able to give high yeast production and low alcoholic content. However, to develop such control system, the complex nature of the yeast metabolism that will affect the system stability has to be considered. Q-learning (QL) is implemented to optimize the yeast production. The main purpose of QL is to reduce the dependency of bioprocess control on human expertise and the amount of data needed for effective control. QL has the learning ability that builds up experience of the process by interacting with the process environment whereby the optimal route seeks through the reward and penalty calculation. In this work, the optimal trajectory suggested by QL was also compared to the exponential feeding rate and their concentration profiles. The performance of the QL controller in rejecting disturbance is also shown.
