Study And Application On The Control Of The Circulating Fluidized Bed

Circulating Fluidized Bed Boiler is a control object that has points of distributing parameter and nonlinear and time-variable and strong delay and coupling tightly multivariable. Through the study on the character of hydrokinetics and heat transfer and combustion and dynamic of CFBB, three kind of single fuzzy controllers and a kind of synthetically fuzzy controller are designed, and control system is analyzed in some one power plant, and the three kind of control scheme are simulated on deferent objects. The simulation shows that synthetically fuzzy controller can provide us a better control performance and stronger robust.
