Abstract:
The paper presents a solution to control the 18O isotope concentration at the output of a separation column. The proposed mathematical model which describes the work of the separation column is a distributed parameter one and it approximates with high accuracy the work of the real plant. The isotope separation process is included in a complex control structure which generates high control performances. In order to improve significantly the separation column productivity, an original solution for the efficient rejection of the disturbances effects, is proposed. Also, a solution to determine the instantaneous value of the separation column length constant is proposed, solution which opens the possibility to implement new control strategies.
