An industrial and academic perspective on plantwide control
The purpose of this paper is to stress the importance of selecting the right plantwide control structure and the need for a formalized approach that can encompass the many issues that arise in plantwide control design. Since the concept of process control design based on a holistic view of the process came about, the variety of procedures and approaches to the design problem has illustrated the...
متن کاملOptimal Operation of a Three-Product Dividing-Wall Column with Self-Optimizing Control Structure Design
This paper deals with optimal operation of a three-product Dividing-Wall Column (DWC). The main idea is to design a control structure, through a systematic procedure for plantwide control, with an objective to achieve desired product purities with the minimum use of energy. Exact local method is used to find the best controlled variables as single measurement or combination of measurements ...
متن کاملPlantwide control: Towards a systematic procedure
Plantwide control deals with the structural decisions of the control system, including what to control and how to pair the variables to form control loops. Although these are very important issues, these decisions are in most cases made in an ad-hoc fashion, based on experience and engineering insight, without considering the details of each problem. In the paper, a systematic procedure towards...
متن کاملPlantwide Operability Analysis based on a Network Perspective: a Study on the Tennessee Eastman Process
Complex process plants increasingly appear in modern chemical industry due to the considerable economic efficiency that complex and interactive process designs can offer. Interactions between process units (e.g., material recycle and energy integration) often cause significant difficulties in plantwide control. As such, it is important to study plantwide operability (i.e., whether a plantwide p...
متن کاملPlantwide control: the search for the self-optimizing control structure
Plantwide control is concerned with the structural decisions involved in the control system design of a chemical plant (C.S. Foss, Critique of chemical process control theory, AIChE Journal 19(2), 1973) 209±214; ``Which variables should be controlled, which variables should be measured, which inputs should be manipulated, and which links should be made between them?'' In particular, the ®rst is...
