Mar 01, 2013· 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 aformerstudy(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 …

In order to estimate the values of these time varying parameters and the internal states of the coal mill an extended Kalman filter was designed. The proposed solution is observed to achieve very good agreement with measurements and can be used for various applications such as model-based control, performance monitoring, fault detection, and maintenance scheduling.

An area of power plant control that has received much less attention from mod elling and control specialists is the coal mills. This is in spite of the fact that it is now accepted that coal mills and their poor dynamic response are major factors in the slow load take-up rate and they are also a regular cause of plant shut-down (Maffezzoni, 1986).
