Model based control of rotary furnaces for magnesia sintering

Rotary furnace simulation model was used for a model-based control on behalf of the on-line interactive communication. Developed model is used for the support of direct and supervisory control. On the direct control level model is used for process observation and process prediction. On the supervisory level model is used for process planning, and execution of the task segments through the autonomous controllers. For the purposes of outlining tasks, a human operator controls a simulation model to generate a sequential list of desired sub-goals for a furnace. A graphic user interface displays operational state and process parameters. The human operator is specifying controller´s set-points. The autonomous control capabilities of the furnace are used to coordinate the actual trajectory between set-points. Provision is made to preview the proposed trajectory for approval or modification before the execution.
