On-line optimal control for fed-batch culture of baker's yeast production

A method of on‐line optimal control for fed‐batch culture of bakers yeast production is proposed. The feed rate is taken as the control variable. The specific growth rate of the yeast is the output variable and is determined from the balance equation of oxygen. A moving model is obtained by using th...

Zusammenfassung:	A method of on‐line optimal control for fed‐batch culture of bakers yeast production is proposed. The feed rate is taken as the control variable. The specific growth rate of the yeast is the output variable and is determined from the balance equation of oxygen. A moving model is obtained by using the data from the feed rate and the specific growth rate. Based on the moving model, an optimal feed rate for fed‐batch culture is then achieved.
