✦ Synopsis

The classical approach to end-point optimization of batch processes leads to a two-point boundary value problem. The numerical solution of this two-point boundary value problem provides the time profile of the manipulated input which has to be implemented in an open-loop fashion. However, due to batch-to-batch variations in the system parameters and initial conditions (which is a typical characteristic of many commercial batch processes), the implementation of this open-loop profile can lead to suboptimal performance. Thus it is desirable to have afeedback which provides the optimal input profile. In a previous paper, we had synthesized optimal state feedback laws for the case where the state model is a linear function of the manipulated input. In this paper, optimal state feedback laws for end-point optimization of dynamic ____.

## Abstract Since the yeast __Phaffia rhodozyma__ was first described some 35 years ago, there has been significant interest in the development of commercial processes to exploit its ability to produce carotenoids (∼80% astaxanthin). However, the optimal conditions for carotenoid production are not

## Abstract Using the proton extrusion of growing yeast cultures (calculated from the alkali consumption required to maintain a constant pH‐value) it is possible to describe the growth of yeasts and the growth‐related substrate consumption on‐line and to do so more exactly than by determining these
