| Outline of Final Research Achievements |
An advanced batch process control technique, namely scenario based batch process control, has been developed. Seeded batch cooling crystallization process has been chosen as a target process, and minimizing the amount of fines has been set as the control objective. Robust optimal temperature swing operations have been found as a result of PSO (Particle Swarm Optimization) calculations.
The scenario-based control scheme is realized by making a sensor measurement and applying predetermined feedback actions during the batch. For the crystallization process, initial supersaturation is estimated by turbidity measurements and feedback action is made according to the level of the estimated supersaturation. Monte-Carlo simulations have been performed to evaluate the proposed operation.
