The study was devoted to test the effect of the process variables on the desublimator(cold trap) efficiency under vacuum technique. Since several intermediate processparameters could not be measured or inspected, then it was necessary to predict them bythe gray model. Although the novel approach (tendency model) for the desublimator wasless accurate than the detailed one, but it showed agreement results when compared withthe experimental data. The accuracy of model could be increased by increasing theprocess variable monitors. The tendency model was more effective to deal with the lackof knowledge about the process when implemented with the optimal control system.
