This paper proposes an adaptive algorithm to compensate roll eccentricity perturbations in web transport systems. Roll eccentricity creates tension disturbance whose frequency may vary slowly due to the rotation speed of the roll. The adaptive algorithm is based on a phase-locked loop structure, it estimates simultaneously the phase and magnitude of the disturbance and then cancels it. The frequency analysis and the parameter design of the algorithm are also discussed. The ability of the algorithm to reject the eccentricity tension disturbances is shown through simulation results.
