Multivariable MD control uses Honeywell’s new Alpha MPC controller to minimize the future predicted variation of all controlled variables in the paper making process while honoring both quality constraints as well as physical constraints on manipulated variables. An economic optimization layer offers dynamic control for processes with sufficient degrees of freedom.
In addition, automatic grade change control can be executed with supervisory MD controls in open or closed loop for speedy, reliable grade changes.
Multivariable CD controls coordinate the corrective actions of multiple CD actuators and extends their effective control range to provide the best overall sheet quality.
The IntelliMap process identification and tuning tool efficiently commissions CD controls, while Adaptive Alignment continuously monitors control performance to automatically detect and correct alignment changes.
