Design and Simulation of Fuzzy Decoupling for Combustion Process of Circulating Fluidized Bed Boiler

Decoupling is an important link in the control of combustion process of circulating fluidized bed boiler (CFBB). In this paper, the method of fuzzy is used in decoupling process, and the fuzzy decoupling device is designed based on the model of object with certain load. Then the control effect is compared with the simulation result which without decoupling device, and the contrast results showed that the method has a good decoupling capability. The method is easy to realize and simple to design, besides it has a good characteristics in adjusting the object model, it is valuable in the actual industry.
