Abstract
The paper presents proposal of a model of the fluidized bed boiler adapted
for use in model-based controllers e.g. predictive, adaptive or internal
model control (IMC). The model has been derived in the form of transfer
function matrix which allows its direct implementation in the controller
structure. Formulated model takes into consideration the principal
cross-coupling between process variables which enables the opportunity to
search for feasibility of decoupling control. The results of the
identification of the dynamics of the 2 MW industrial bubbling fluidized
bed boiler using the proposed model form was presented. According to the
experimental data it was found that despite of introduced simplifications
presented model allows the boiler behavior prediction.
