In this study, a multivariable predictive controller is used in the simplified ball mill model. The control block diagram is shown in Fig. 9. The setpoint of primary air flow and pulverized coal flow is determined by unit load command. The setpoint of outlet temperature and fill level is determined by the safe and economic operation requirements.
