The mediumspeed coal mill pulverizing system is widely used in coalfired power plants in China. Thus, the study of the operating characteristics, construction of the model, and optimization of control system are important. The coal mill grinds raw coal into pulverized coal, which is then dried to meet certain requirements.

As mentioned in Section 1, the change of coal in a thermal power plant typically happens over a period of several hours (referred to as coal transition) and there is an irregular time lag between the coal change at the bunker level and that at the mill or boiler level (Tuttle et al., 2020). Therefore, realtime detection of change of coal in an ...
