PSO-PID Control of CFB Boiler Combustion-Steam Water System Based on α-order Inverse Neural Network(NN) Decoupling

Based on α-order inverse system decoupling principle,an α-order inverse neural network system was proposed.Simulation results of this system to circulating fluidized bed boiler's bed temperature disturbance and main steam pressure disturbance show that,constructed α-order integral inverse system using neural network can solve coupling problem of the combustion-steam water system,roles are clear,in which neural network approach nonlinear function and integral differential components are used to describe dynamic characteristic,its structure is simple,and little prior knowledge of original system is needed,it has engineering application value.
