Abstract:
In order to adjust temperatures of superheating sections in a once-through steam generator, a combined feedback-feedforward fuzzy logic control approach is presented in this paper. This structure is employed in a coupled two-stage attemperation strategy in order to distribute the total spray demand between attemperation stages. The inverse-feedforward controller is developed by performing optimization based on closed-loop data. The local fuzzy logic controllers are considered for each stage in order to eliminate the effect of unmeasured disturbances in cooperation with the FF controller. The proposed control system is applied to the system model and results are compared with results of others recent researches as well as with the response of actual system to show the performance of designed control system.
