“…There are several studies of adaptive control of a batch chemical reactor (Katoh, Nakao, & Hanawa, 1989;Regev, Lewin, & Lavie, 1989;Rao & Lee, 1991) in which systems learn to maintain a predetermined optimum temperature profile. Ryhiner, Dunn, Heinzle, and Rohani (1992) have studied adaptive learning in a biochemical process by the method of steepest ascent.…”
