The control of the temperature profile of the rectification column dish type
SHEVCHUK V.P. SHAROVINA S.O.

The efficiency criterion of the functioning top part rectification column dish type control is offered. Process control quality of an imitating modeling method is researched in conditions that approximate to real (drift object characteristics and measurement interference). The adaptive control algorithm of the top point temperature profile of the rectification column which is based on a compensation principle of indignations coming from a supply plate is offered. The mathematical model of an object control is verified. The model is applied in the control criterion efficiency of the top part of a column. The automation device control of the rectification column dish type is researched. The device is realized an adaptive control of the top point temperature profile of a column. Also device is realized an adaptive supply plate temperature control and robust system stabilization of the bottom point temperature profile of a column.
Keywords: adaptive control of the temperature profile, efficiency criterion of the functioning, control of the rectification column, process control quality, compensation principle of indignations from a feed of column.
