A Study on Double-Stage Fuzzy Control of Drum Level in Waste Heat Boiler
The waste heat boiler is an important part of waste heat power station in cement plant. So it is highly important to control the drum level of waste heat boiler within the allowed range. A Double-Stage fuzzy controller which is used to control the drum level of the waste heat boiler is presented in this paper. This method adds a secondary fuzzy controller to adjust the weight of the first fuzzy controller’s factor on the basis of a general fuzzy controller. Simulation results show that the double-stage fuzzy control system has fast respond speed, high precision and strong anti-jamming capability.
