Modeling and control of ball mill system considering coal ...

2016-8-1 · A duplex inlet and outlet ball mill pulverize system model is established by considering the effect of raw coal moisture on the dynamic characteristic of the mill. The EKF approach is employed to estimate and verify the model states, and an extended state space predictive controller is applied to the established model.
