Abstract:
A method of controlling an electro-hydraulic actuator (101). An electric voltage applied to the actuator (101) is established by superimposing a control variable with an oscillatory signal. A hydraulic pressure, influenced by the actuator (101), is measured. The oscillatory signal is adapted as a function of the measured hydraulic pressure.
