Abstract
A method is provided for adapting controller parameters of a drive to different operating states. A control loop includes a PID controller whose I gain factor is adapted to a drive velocity and/or whose D gain factor is adapted to a drive current, and consequently to a drive load. The I gain factor is determined based on the drive velocity and the D gain factor is determined based on the drive current, in each case at least in one area, the I gain factor falling with the drive velocity and the D gain factor rising with the drive current.

A method for adapting controller parameters of a drive to different operating states, a control loop of the drive including a PID controller having an I gain factor adapted to a drive velocity and a D gain factor adapted to a drive current and consequently to a drive load, comprising:
- (a) determining the I gain factor based on the drive velocity, the I gain factor falling with the drive velocity;
- and
- (b) determining the D gain factor based on the drive current, the D gain factor rising with the drive current;
- wherein the determining (b) includes:
- determining the D gain factor as a first D gain factor below a first limiting drive current;
- determining the D gain factor as a second D gain factor above a second limiting drive current, the second D gain factor greater than the first D gain factor;
- and
- determining a continuous transition between the first D gain factor and the second D gain factor between the first limiting drive current and the second limiting drive current.
