Abstract

This article presents a new approach to cross directional response identification and control on a paper machine based on continuous wavelet transform. The response shape developed as a surface wave originating from the slice lip deflection is used as the mother wavelet equation. Identification results with paper machine data shows that the method is effective. Application of the continuous wavelet to the CD control problem presents a new formulation of the control algorithm. The mapping process is eliminated in the new approach and replaced with a simple scaling operation.
