Abstract: System determines the position of a control element of an electrically driven actuator. The actuator may be switched on by a controlled switch when a lower threshold value is reached and may be switched off when an upper threshold value is reached. An on-period and an off-period are determined as a function of the lower threshold value, the upper threshold value, and the electric switching behavior of the actuator depending on the position of the control element. From the on-period and the off-period, the position of the control element are determined from a comparison of the quotient of the on-period or off-period and the sum of the on-period and off-period, and from a comparison of the sum of the on-period and the off-period with corresponding stored reference data. The system includes accompanying circuitry for application of the process, and an accompanying device, in particular a hydraulic valve.
