The bed temperature is an important parameter of the circulating fluidized bed(CFB) boiler. In this study
the closed-loop identification method of the multiple-input multiple-output(MIMO) system is used to obtain a twoinput two-output system model
in which the coal supply and the primary air flow of the CFB boiler are the inputs
and the bed temperature and the main steam pressure are the outputs. The field operating data of a 300 MW CFB gangue-fired power plant under closed-loop automatic control are used for the identification of model parameter. Intelligent identification of the standard particle swarm optimization(PSO) algorithm is used to obtain the optimal model parameters to multi-variable system of bed temperature through optimization. Finally
the effectiveness of the built model is verified by the actual operating data.
