Study On The Intelligent Control Of Combustion System Of Circulating Fluidized Bed Boiler

Circulating fluidized bed boiler control strategies based on classical control theory or modern control theory all need exact mathematical models of controlled objects. It is very difficult to establish the exact mathematical models of controlled objects because the combustion system of circulating fluidized bed boiler is an object that has many features: distributed parameters, nonlinear, time-varying and a lot of tightly coupled variables. To the combustion control system of circulating fluidized bed boiler this text designs two types fuzzy-PID controllers: the self-tuning parameter fuzzy-PID controller and the fuzzy-PID the controller according to the model of T-S. And we carry out simulation research to the combustion control system of circulating fluidized bed boiler.The results indicate that the control quality, the speediness, the robustness and the ability of anti-disturbance of fuzzy neural network control system are all superior to the general PID control system.
