Today’s market and the state-of-the-(art in paper machine technology set contradictory requirements on paper process optimization. In this paper, requirements of grade change automation for paper and board machines are discussed. A new method to implement a model-predictive controller is presented. The method allows the use of nonlinear models and strict constraints in performance criterion. The method is demonstrated by implementing grade change automation for a board machine. Test runs are accomplished using a new simulation environment for the pulp and paper proc-esses, the Advanced Paper Mill Simulator (APMS). Dy-namic simulation using high-fidelity models is a powerful tool for process and automation design as well as for opera-tor support and training.
