The control of the pulverizing system is a bottle neck in the control of the power generation process, since the key controlled variables are either unmeasurable or inaccurately measured. To address this problem, this paper studies the control-oriented modeling and the inferential control of the pulverizing system, aiming at improving the control precision.
