Abstract

A method is used to control a torque of an electric motor of an electro-hydraulic system. The method includes selecting a value of a set point torque depending on a current pressure in a hydraulic circuit of the electro-hydraulic system. The method also includes determining a control signal for controlling the torque of the electric motor using a target torque and the set point torque.
