Patent ID: 8862249

Claim:
A method comprising: initiating, by at least one processing device, a spatial impulse test of a fiber orientation (FO) process; initiating, by the at least one processing device, a spatial long wavelength test of the FO process to identify long wavelength responses of the FO process; generating, by the at least one processing device, a model associated with cross-directional fiber orientation of a web based on spatial frequency characteristics of the FO process identified in the spatial impulse test and the spatial long wavelength test; providing, by the at least one processing device, the model to a controller for control of the FO process; controlling, by the controller, the FO process based on a controller model generated using the model; and dynamically adjusting, by the controller, at least one parameter of the controller model during operation of the FO process, wherein dynamically adjusting the at least one parameter of the controller model changes an operation of at least one equipment associated with the FO process.
