Abstract
A controlling system having a controller which acts on a controlled system as a function of a manipulated variable and a number of controller parameters is intended to provide a given control quality and a given control response in all operating states of the controlled system. For this purpose, the response characteristic of the controlled system is determined in a given time window during operation of the controller by comparing a wavelet transformation of the temporal response of the manipulated variable with a wavelet transformation of the temporal response of a controlled variable of the controller. An instant assigned to the respective wavelet transformation is detected, and the or each controller parameter is set as a function of the response characteristic.
