Automatic speed loop gain adjustment method and apparatus for a feedback control system |
摘要 |
Automatic speed loop gain adjustment of a feedback control system begins by setting up a phase margin range and a gain margin range. A speed open loop condition is provided by separating a speed command value from a speed feedback value. White noise is input into the feedback control system where the speed open loop condition has been made. A phase margin and a gain margin are then detected and comparisons are made with the phase margin range and the gain margin range, respectively. The speed loop gain is adjusted if the comparison results for either one of the detected phase margin and the detected gain margin fall outside of the associated phase margin range or gain margin range. Once the adjustment of the speed loop gain is complete, the position loop gain of the position control loop is adjusted on the basis of the adjusted speed loop gain.
