Fuzzy control acquisition point problem
Thread Content
The process layout in our facility is as follows: coke oven, drum cooling, desulfurization, ammonium sulfate production, and crude benzene. Fuzzy control systems are used for the coke oven and drum cooling processes. There are two coke ovens; each oven has a gas collector pressure and a regulating valve for the gas collector. There is a suction level before the primary cooler, and the coal gas fan also has a speed control system. What is mainly used to regulate the pressure in the gas collection pipe? What is the reference point used for controlling this extraction?
The control of the collector pipe pressure is primarily achieved through the control valve installed on the collector pipe, with the collector pipe pressure itself serving as the reference point. But factors such as the delay over long distances in the pipelines, the lag in pressure changes, and the instability in the combustion in coke ovens must be taken into account.
The fan and the flap need to be adjusted simultaneously, with the fan taking priority and the flap being adjusted slightly.
Thank you to the person above; it’s useful for reference
