MPC Control for Superheated Steam Temperature

Abstract

This contribution deals with design and implementation of control system for superheated steam temperature, which is most often carried out by injection of the feed water. In the proposed control system, a common cascade control system is replaced by a predictive controller. This can quickly respond to rapid and unpredictable changes in steam consumption. The accuracy of the predictive controller design has been verified not only by digital simulation but directly in real process. The quality of the newly designed controller was compared to the originally implemented cascade control.
