The Study of Level Control Strategy for Supercharged Boiler Drum Based on Fuzzy Control

Abstract

The supercharged boiler drum level as the controlled object, a high-precision simulation model was established considering the impacts of the distribution of the metal wall condensation inside the drum on the water level changes. Based on simulation model, a simulation program for pressurized boiler was prepared. The simulation results show that the performance of the state fuzzy controller is better than the PID controller.
