Rm. Price et C. Georgakis, PLANTWIDE REGULATORY CONTROL DESIGN PROCEDURE USING A TIERED FRAMEWORK, Industrial & engineering chemistry research, 32(11), 1993, pp. 2693-2705
Two frameworks for process control design have been identified, and th
ey are used to structure the control design decision sequence in a way
which preserves the ''plantwide'' character of the problem and soluti
on. A CSTR/column process example has been studied in depth, and a pro
cedure for the design of the coupled system regulatory control structu
re (throughput, inventory, and product quality controls) has been deve
loped. The procedure is based on a tiered framework for plantwide cont
rol system design and is justified and supported by an extensive set o
f dynamic simulations. Specific guidelines for designing inventory con
trol structures are presented. The best-performing structures are show
n to be those which are 'self-consistent'' and designed to minimize th
e propagation of disturbances through the system. The design procedure
for throughput and inventory control design is believed to be fully a
pplicable to other processes. Results from specific application exampl
es will be presented in forthcoming publications (Price et al., 1993).
