Abstract

In the process for controlling the tape thickness it has been found that the complex roll eccentricities produced by the superimposition of several interfering influences are not adequately compensated for by the control methods which have hitherto become known. To be able to compensate for even complex roll eccentricities, it is proposed to determine the transfer function of the fault signal embodying the roll eccentricity and to derive from this transfer function controller parameters on the basis of which roll eccentricity compensation signals can be calculated. Using this means, the roll eccentricities are compensated for in accordance with the principle of adaptive control. <IMAGE>
