Abstract
This paper presents a new adaptive cascade temperature control system for jacketed stirred tank reactors in which multiple products are produced. The adaptive control system consists of two cascade input−output linearizing controllers and an inversion-based parameter estimator that estimates the rate of heat production by reactions and the overall jacket−reactor heat-transfer coefficient. Without a need for retuning, it can provide tight temperature control in highly exothermic, multiproduct, jacketed, stirred-tank reactors in which the reaction rate and the overall heat-transfer coefficient are unknown and vary significantly. The application and performance of the adaptive cascade control system are shown and compared with those of a proportional-integral (PI) cascade control system by an exothermic chemical reactor with varying overall heat-transfer coefficient. Compared to a PI cascade control system, the adaptive cascade control system exhibits better performance and is much easier to tune.
