Abstract:
A method for automatically adjusting a speed controller of an elastomechanical controlled system, comprising the steps of:(a) calculating a first transfer function for a mechanical frequency response of the elastomechanical controlled system; (b) identifying first pole positions and first zero positions in the mechanical frequency response; (c) storing the first pole positions in a buffer memory; (d) calculating a second transfer function for a closed speed control circuit; (e) identifying second pole positions and second zero positions in the second transfer function; (f) selecting a particular pole position of the second pole positions having a largest amplitude; (g) assigning a corresponding pole position of the first pole positions to the particular pole position; (h) setting filter parameters for the corresponding pole position as a function of a respective pole position frequency and a respective zero position frequency for filtering predetermined current setpoints; and (i) repeating steps (e)-(h) until the speed controller is adjusted with a predetermined accuracy and without further filtering of the predetermined current setpoints.
