Method for controlling a gear pump

A method for controlling a gear pump by way of a control device to compensate a tooth engagement-induced volume flow pulsation, wherein the control device includes an acquisition unit, a computing device, and a memory device, wherein the method comprises at least the following steps:

• a. by way of the acquisition unit, acquiring a gear angle and an actual speed of the gear pump;
• b. by way of the memory device, maintaining a relationship between a respective modulation angle and an amplitude of a pilot control torque of the gear pump to compensate the volume flow pulsation to an actual speed of the gear pump;
• c. by way of the computing device, modulating the pilot control torque on a basis of the acquired gear angle, a predetermined correction angle, the modulation angle, a number of teeth of the gear pump and the amplitude, wherein the modulation angle is calculated using a PT element with the actual speed as an input variable;
• and
• d. by way of a drive unit, driving the gear pump with a drive torque overlaid with the modulated pilot control torque.
