Beschreibung
Zusammenfassung:	Disclosed is a control device for a peristaltic pump which delivers a medium in pulsating pressure cycles, the control device controlling a speed of the peristaltic pump in such a way that a maximum volume flow (Qmax) is achieved without exceeding a pressure limit (pGrenz) in the delivery line. In certain embodiments, it is proposed to calculate a prediction pressure (pfutur) for each pressure cycle (P) for an expected maximum pressure within the pressure cycle (P) on the basis of at least the pressure (pist) in the output line and to limit the maximum volume flow (Qmax) by using the prediction pressure so that the pressure (pist) in the output line does not exceed the pressure limit (pGrenz) in the pressure cycle (P).
