Improving the quality of the steam temperature regulation in the TsKTI-100 boiler thanks to use of fuzzy adjuster

Abstract

The results of designing and setting up fuzzy logic adjusters for controlling the steam temperature in the CCTI-100 gas-tube boiler at Berezniki Soda Plant JSC are presented. The setting of the adjusters is made by a method based on the use of a geometric progression. The quality of management is evaluated on the grounds of direct and indirect indicators system. Comparison of their values with the corresponding quality indicators for a conventional PID adjuster showed a significant advantage of fuzzy regulation.
