Model-based Control of an Energy-integrated Batch Reactor — Feed Effluent Heat Exchanger System in a Campaign Mode *

摘要

In this paper, a novel model-based cascade control strategy has been developed for an energy-integrated batch reactor-feed effluent heat exchanger system. The presence of two time scales facilitates implementation of such a cascade strategy. An input-output model is developed for the slow dynamics of the system and is used for the design of a model-based controller to achieve desired product purity. The effectiveness of the proposed control strategy for disturbance rejection and operating point transitions is demonstrated with the help of simulation studies. The proposed strategy promises direct saving of energy, material and time.
