The control arrangement may be used for vehicles or in other steering systems and includes a steering motor that is adjusted as a function of hand operated steering mechanism, the steering mechanism controlling a directional section and a metering motor section. The directional section is fluidly connected between the steering motor and both of a tank and the metering motor section. A pump is connected between a tank and the metering motor section. The one sides of electromagnetic plus and negative valves are fluidly connected between the fluid connection of the metering motor section and the directional section while the opposite sides are respectively connected to the connection of the pump and the metering motor section and the connection of the directional section to the tank. A processing device for controlling the valves is provided for sensing the steering angle error. The control arrangement provides a simple structural arrangement to compensate for leakage.
