Abstract
A method for determining optimum controller parameters for a digital rotational speed control is described, in which various test signals are applied to a speed control loop and the resulting speed characteristic is determined. The speed characteristic is subsequently weighted with respect to rise time and transient response for various controller parameters, and the most favorable controller parameters are subsequently set in the controller of the control loop. The integral-action time of the control loop is used as a criterion in performing the weighting operation.
