Adaptive Fuzzy PID Control for Boiler Deaerator

摘要

The boiler deaerator temperature control system is a non-linear, time-varying,delay control process. It can not achieve satisfying effect using traditional control algorithm to control deaerator water temperature, the paper proposes an adaptive fuzzy PID control algorithm, the control algorithm can adjust control parameters online to adapt to the changes of the deaerator water temperature. This paper carried out simulation experiment using adaptive fuzzy PID control algorithm, the fuzzy PID control algorithm and the PID control algorithm respectively in Matlab/Simulink, the simulation results are illustrated to show that the system works well,has very good static and dynamic performance,strong robustness and self-adaptive ability.
