Title Of Article :
Gray-box identification of dynamic models for the bleaching operation in a pulp mill
Latin Abstract :
The development and application of gray-box identification techniques for modelling the bleaching operation in a Bleached
Chemi-Thermo Mechanical Pulp (BCTMP) mill are explained. The process is characterized as a delay dominant recycle process with
significant input nonlinearities. The identification was carried out using routine operating data in which the outputs were measured
irregularly. The effects of these characteristics and consequent modifications of the system identification techniques are discussed.
The resulting models are being used for online prediction and model-based controller design at the mill with satisfactory
performance.
