Abstract
A method for controlling a servo system (10) having friction, in which the non-linear characteristic (20) of the position controller (12) is defined such that the magnitude of the variable Ns, Vs supplied to the servo system (10) having friction in the case of a control deviation .DELTA.x lying outside a predeterminable target region (21) produces a torque or a force which is adequate to tear the servo system free of the stiction torque or stiction and such that the movement energy of the servo system (10) can be dissipated in the target region (21). The additional use of an integral component, which is preferably a function of the control deviation .DELTA.x, increases the steady state accuracy.
