  • Nonlinear coal mill modeling and its application to model

     · Finally conventional coal mill control is discussed in Lindsley (2000) and Liptak (2006). In the present work a novel nonlinear coal mill model is derived for model-based real time applications based on a former study (Mercangoez Poland 2011). One of the objectives is to consider a trade-off between model complexity and model accuracy based on real measurements from an actual hard coal burning
