  • Patent number: 8616033
    Abstract: A method for vibration damping and shape control of a suspended metal strip is provided. The method includes the steps of: measuring distance to the metal strip by a plurality of non-contact sensors, providing distance measurements; generating a deflection profile based on the distance measurements; decomposing the deflection profile to a number of base shapes; and controlling the deflection profile by a plurality of non-contact actuators. The step of controlling includes providing for each of the base shapes a corresponding combination of force profiles.
    Type: Grant
