Robust cross-directional control of large scale paper machines

摘要

Paper machines pose a challenging multivariable control problem.The processes are poorly conditioned and truly large scale, in that thenumber of inputs and outputs can range from 100-1000. Their large scalenature makes it important to account for inaccuracies in the processmodels. A control algorithm is developed that addresses modelinaccuracies in a numerically efficient and effective manner
