Estimating modulus of elasticity, torque loss, and tension using an Extended Kalman Filter. Paper presented at the Fifth International Conference on Web Handling (IWEB), Stillwater, OK.https://hdl.handle.net/20.500.14446/321791A set of sub-optimal Extended Kalman Filters (EKF's) are described. The filters are used to estimate web tension, modulus of elasticity, and loss torque for all sections in a small web processing line located at Rockwell Automation's Euclid Research Facility. Conditions necessary for observability, and estimate convergence are discussed.application/pdfIn the Oklahoma State University Library's institutional repository this paper is made available through the open access principles and the terms of agreement/consent between the author(s) and the publisher.
