Abstract (EN): The study of four structures of linear model predictive control (LMPC) for a batch white sugar crystallization process is reported in this paper. Two SISO and two MIMO control schemes were compared with respect to the final process quality achieved. The linear models required in the controller structures were extracted applying two identification alternatives. The SISO cases seem to guarantee more satisfactory end point quality of the process. However, only the LMPC of the supersaturation manipulating the steam flowrate makes feasible all conflicting control objectives.
