Abstract

A method is proposed for determining parameters for the auxiliary control of the position guidance variable of an axis of a numerically controlled machine path. If the auxiliary control parameters up to the n.sup.th order are known for the i-th axis, auxiliary control parameter of the order of n+1 can be determined by predetermining a guidance variable signal in the form of a parabola of the order of n+1 for the axis. By including the amplification (K) of the control unit (11) and the n+1-th derivation of the guidance variable signal over time, a auxiliary control parameter of the order of n+1 can be determined from the steady-state error which occurs.
