This project provided for the implementation of an advanced, model predictive multi-variant controller that works with the mill's existing distributed control system. The method provides real time and online predictive models and modifies control actions to maximize quality and minimize energy costs. Using software sensors, the system can predict difficult-to-measure quality and process variables and make necessary process control decisions to accurately control pulp quality while minimizing electrical usage. This method of control has allowed Augusta Newsprint Company to optimize the operation of its' Thermo Mechanical Pulp mill for lower energy consumption and lower pulp quality variance.
