| description | The invention relates in particular to a control device (8) for a peristaltic pump (5) for delivering a medium in a pulsating pressure cycle, which control device (8) controls the speed of the peristaltic pump (5) in such a way that a maximum volumetric flow rate (Qmax) is achieved without exceeding a pressure limit (pGrenz) in the delivery line (9). One task is to guide the actual pressure in the output line (9) as close as possible to the pressure limit (pGrenz) or to minimize the distance thereto. In order to solve this problem, it is proposed to calculate a predicted pressure (psutur) for each pressure cycle (P) of an expected maximum pressure within the pressure cycle (P) on the basis of at least the pressure (pist) in the output line (9), and to limit the maximum volumetric flow (Qmax) by using the predicted pressure such that the pressure (pist) in the output line (9) does not exceed the pressure limit (pGrenz) in the pressure cycle (P). The invention also relates to related aspects.
