Abstract
A method for detecting optimal controller parameters for a digital speed control is proposed, wherein an rpm control circuit is charged with different test signals, and the resulting rpm progression is determined. This rpm progression is subsequently evaluated with respect to triggering time and transient response for different controller parameters, and thereafter the most advantageous controller parameters are set in the controller of the control circuit.
