Tendency modelling of desublimator for optimization and control

Abstract EN

The study was devoted to test the effect of the process variables on the desublimator (cold trap) efficiency under vacuum technique.

Since several intermediate process parameters could not be measured or inspected, then it was necessary to predict them by the gray model.

Although the novel approach (tendency model) for the desublimator was less accurate than the detailed one, but it showed agreement results when compared with the experimental data.

The accuracy of model could be increased by increasing the process variable monitors.

The tendency model was more effective to deal with the lack of knowledge about the process when implemented with the optimal control system.
