Beschreibung
Zusammenfassung:	Disclosed herein is a hydraulic actuator system comprising a servoactuator including a hydraulic actuator and a control valve, wherein the supply of hydraulic fluid to the servoactuator from a fluid supply is adjustable through a control system based on feedback information relating to the servoactuator. The hydraulic actuator system may e.g. be used for controlling blade pitch in a variable pitch propeller system such as may be found on a turboprop aircraft or a ship.
