摘要：A circuit arrangement for controlling the output torque of a hydrostatic machine connected to a hydraulic system having an impressed operating pressure. The circuit arrangement has a control element for changing the output torque of the machine based upon operating parameters corresponding to pressure, speed, temperature and the like. Control means are supplied with a desired torque value for generating a control signal for actuating the control element. Pick-up means are connected to the control means and to the control element for picking up a pivotal angle alpha or an eccentricity E, respectively, representing an actual displacement volume of the hydrostatic machine. The pivotal angle alpha and the eccentricity E are measured in either an analog or a digital manner. When measured in an analog manner, the desired value of the pivotal angle is alpha =M/P and the desired value of the eccentricity is E=M/P, where M is the torque and P is the pressure. When measured in a digital manner, the desired value for the pivotal angle and the eccentricity, respectively, are determined from previously determined measured values.
