The application of the neural network control method in the combustion process of circulating fluidized bed boiler

The article analyses the feature of the combustion control system of circulating fluidized bed boiler.To the control system of the main steam pressure,this paper proposes a new type of PID control method based on the improved BP neural network,which is a combination of the neural network and the PID strategy.It has the merits of both neural network and PID controller.A simulation study showed that the platform is good in overcoming the object inertia,time—variability,and random disturbance,and can considerably improve the control quality.
