ABSTRACT:
Position of an object is detected by a position detector (10) and position data detected by this position detector is stored in a memory circuit (11). A time data supply section (21) supplies time data (.DELTA.t) as a lead compensation parameter. A compensation circuit (22) reads out position data (Dx (-.DELTA.T)) for a preceding time corresponding to the supplied time data (.DELTA.t) from the memory circuit (11) and corrects at least one of present position data (Dx) and target position data (Sx) in accordance with the difference between the read out position data and the present position data detected by the position detector thereby performing lead compensation. A control signal relating to the position of the object is generated in accordance with the present position data corrected by the compensation cirucit and the target position data and the positioning control is made by this control signal.
