Dynamic model identification of the low-power fluidized bed boiler
Languages of publication
The paper presents results of the identification of the multivariable model of the fluidized bed boiler derived in the form of transfer function matrix. Conditions of the experiment that ensure the identifiability of model dynamics while limiting the risk of emergency boiler shutdown was proposed. Typical disturbances of the combustion process including division into measurable and immeasurable ones as well as the method to identify the impact of these disturbances on the outputs of the model was formulated. Possible application of the model in the model-based controllers such as predictive or adaptive IMC (Internal Model Control) was indicated.
