Abstract: A method and an apparatus for improving the command performance of distance controlled positioning drives, as well as the positioning performance in the region of the destination, responds to different interferences, such as changing load and friction conditions, which act from travel to travel on the positioning drive. A distance control is periodically optimized to a constant set of standardized operating parameters and the position errors caused by interferences are eliminated during every travel. The control is a cascade control with fourfold forward correction by direct bias of the generated desired values of the jerk, the acceleration, and the velocity. A distinction is made between predictable deterministic interferences and not predictable stochastic interferences. Deterministic interferences are detected quantitatively by a start up test during the first phase of jerk in a measuring means. A compensation signal is in a function generator which completely compensates the corresponding position error until the end of the travel. Stochastic position errors are equalized in an integrating amplifier until the end of the travel. For a range of destinations, the remaining residual distance control error is increased for a short time in a distance control error multiplier.
