Abstract :
The combustion system of circulating fluidized bed boiler (CFBB) is a complex object with multivariable, large delay, tightly coupling, nonlinear and slow time-varying. It is difficult to build the precise mathematic model of the object and to accurately control the object with the traditional control methods. In this paper, the object is dynamically decoupled by a feed-forward compensator. Then, the object is respectively controlled by three controllers, PID controller, fuzzy controller and self-tuning parameter fuzzy-PID controller. The simulation experiments are carried out through contrast with former controllers in MATLAB simulation environment. The simulation results show that the self-tuning parameter fuzzy-PID controller is superior to the general PID controller and the general fuzzy controller in speediness, stability, adaptability, robustness and ability of anti-disturbance.
