Abstract

In this paper, a new control strategy that employs a mid-course correction to control the particle size distribution in emulsion polymerization is developed. In this approach, online and infrequent measurements are used to obtain the states of the system at the mid-course of the process. Then an optimization is performed to obtain the optimal trajectory of the input from the mid-course up to the end of the process. For this optimization, a hybrid model is used. This ...
