System identifier for paper machine

摘要

A system identifier for a paper machine which allows an operator having no special skills to easily implement step responses in a profile control and which comprises a mechanism for storing theoretical positional correspondence determined by paper contraction; calculator device for calculating profiles for slices associated with the operated ends using measured values at the detected end; another calculating device for calculating the conformity of each operated end by multiplying the profile for the slice by an interference coefficient indicating the effect of an operation on an operated end and on the detected end; an output slice selection device to which data of the conformity of each operated end is inputted and which outputs an output slice selection function by performing a neural network calculation wherein self feedback is performed for the operated end and lateral inhibition is performed to inhibit mutual interference between neighboring operated ends within a predetermined range; and a step response output device for performing step response at the operated ends which have survived within the range in which the mutual interference is inhibited using the output slice selection function.
