Adaptation of Control Structure Design Methods to an Industrial Plant Engineering Workflow

Abstract

Methods of systematic control structure design are adapted to suit the industrial workflow of plant design and engineering in the chemical and process industry. The applied methods include a systematic stepwise design methodology and the concept of self-optimizing control. Implementation of these methods is performed in a commercial software framework that consists of Aspen Plus and MATLAB. The control structure design methodology of a sequence of heat-integrated distillation columns is presented as a case study.
