Fuzzy Logic Based Boiler Drum Water Level Control

Based on the analysis of dynamic characteristics of the drum water level, a control strategy of self-adjusting PID fuzzy control of the drum water level in a CFB boiler is presented in this paper. Compared the effectiveness of self-adjusting PID fuzzy control with the general PID on the model of the drum water level in a CFB boiler and the simulation results show that the scheme provides the control system the stronger robustness and better control quality, and improves its dynamic and static performance index.
