Abstract
A Kalman filter algorithm is used for estimation in a feedback control system for a moving web. Matrices of the Kalman filter algorithm are solved with reduced computational complexity. One of the matrices is solved as a diagonal matrix for both state prediction and covariance and another matrix for gain is solved merely as a vector.
