Abstract
Traditional control methods have serious nonlinear and strong coupling problems besides the uncertainty of model in combustion system of the bus-pipe-type coal boiler. A fuzzy PID control plan is proposed. According to the characteristics and controls demands of the T-230-2 boiler combustion system, a FUZZY PID controller is designed. With the help of the fuzzy controller, the PID controller parameters can be adjusted instantaneously to optimize them. It can realize the request control. The paper analyzes the robustness and noise immunity of the bus-pipe-type pressuer through the Matlab simulation. The result indicates that the project has better control effect. It can overcome disturbance effectively and increase system’s dynamic performance.
