Use Model-Predictive Control to Improve Distillation Operations

VIEWS: 9 PAGES: 7

Examine the need to retain the dynamic model for those pairs of variables that have relatively minor gains and transient responses. When based on a first-principles dynamic simulation model, such responses may be correct theoretically, but of no practical significance to an operating multivariable controller. To get a good grasp of the relative effect of the IVs for each CV, it is useful to enter the identified Laplace transforms and an appropriate realistic move size for each IV.
