Daicoviciu Str.,15, 400020 Cluj-Napoca, Romania Keywords: isotope separation column, robust control, networked control Abstract In the present developing plan to apply the cryogenic technology for the production of the 13C, an efficient and safe operation is a strong reason to conceive and to apply a modern computer based control strategy. The authors are concerned with the problem of developing effective and readily implemental techniques for modelling and control of the isotope separation plant. The use of a data network in a control and monitoring loop has gained increasing attentions in recent years due to its cost effective and flexible applications. The present paper presents such a monitoring system applied to 13C Isotope Separation Column and the possible robust control. References [1] D. Axente, M. Abrudean and A.
