Circulating Fluidized Bed Boiler Combustion System Control Algorithm

CFB Burning technology is a high effective and clean technology. In fact, CFB has the ability of adapting to lots kinds of coals, burning effetively, Good adjusty, low cost and cleaning. CFB boiler is a distributed parameter, strong coupling mutilvariable, changed control object. It's structure is very complicated and have lots of factors to effect it's burning .Realizing the auto-control of the burning system is a very important issueThe neural network system has the feature of information synthesizeth learning memory, and adaptation ,it can be used in industrial control. But it's complicated algrighem ,long learning time ,convergence affect it's application PID control is easy to realize and robust. In this article ,a mutilvariable neural network controller is presented. It be used to control the strong coupling time-delay mutilvariable systems. The control systems have perfect performances in nonlinear , mutilvariable coupling system. It can be easily realized and learned in a short time, so there will be a good future in application .It have better effection than PID controiier inburning control of CFB.
