Abstract
The invention relates to method for identifying plural relations in a sheet manufacturing process. Sheet properties are deduced from a response in a pseudo-property profile to a cyclic stimulation. A pseudo-property profile is calculated using a phase lag equal to half the stimulation cycle time, with and without stimulation. The properties of the sheet are deduced from the difference between an excited pseudo-property profile and a reference pseudo-property profile.
