Batch Process (BP) control in literature is performed using PID and MPC with trajectory tracking. Generally, the control trajectories are obtained from an optimization problem which aims for the batch time minimization. Some authors stablished that this kind of trajectories has a negative effect on control performance. Using some definitions from Set Theory it is possible to design a Controllable Reference Trajectory (CRT) for BPs control. CRT has more available input variables to obtain a better control performance. Nevertheless, it has an impact in productivity. This work shows the implementation of the CRT using different control strategies in order to compare with classic paradigm of minimum time reference trajectory. Control performance improved by the CRT application.
