This paper first presents a brief outline of the general characteristics of hydraulic actuation systems based on variable displacement hydraulic motors (VDHMs), then it describes the architecture of an innovative solution proposed for the actuation of the cargo door of an aircraft for which a control technique was developed to further exploit the advantages of such hydraulic motors. The merits of this solution are outlined and a comparison is made with the performance of a conventional system using fixed displacement hydraulic motors.
