An Algorithm for Estimating Cross and Machine Direction Moisture Profiles for Paper Machines

Abstract In this paper we develop an algorithm for estimating, in the presence of noise, cross and machine direction (CD and MD) moisture profiles based on a model described in the literature. The algorithm consists of a least squares parameter identifier for estimating CD profile deviations and a Kalman filter for estimating MD profiles. Simulation results of the algorithm are given. The preliminary results of the application of the algorithm to industrial data are also given. The algorithm developed can be extended to other measurement models
