Instead, dynamic modeling and nominal control of these coal mills have been the topic of numerous of publications. Some examples dealing with modeling of coal mills are (Rees and Fan 2003), (Zhang et al. 2002) and (Tigges et al. 1998). Controllers for the coal mill are designed in (Rees and Fan 2003) and (Hasselbacher et al. 1992).
Coal mills grind the coal into fine powder, and the primary air entering the mill dries and drives the coal into the power plant furnace for combustion. ... As discussed by G.Q. Fan and N.W.
