BO1751 POWER DRIVE UNIT AND CONTROL SYSTEM THEREFOR Abstract of the Invention This invention relates to an energy efficient variable displacement motor-driven power drive unit using a multi-variable feedback control system to control system output position and speed. More particularly, a variable displacement hydraulic motor connected to drive a load has a variable-position wobbler, with the position controlled by electro-hydraulic servo means including an electrically-operable servo valve which receives a control signal from signal summing means which has summed feedback signals representing speed and position of a load with a torque signal representative of wobbler position. The latter signal is mechanically inputted to the servo valve by means of a mechanical connection including a link connected to the wobbler and a spring interconnect- ing the link to the servo valve and with the link carry- ing a servo piston movable in a servo cylinder associated with the servo valve.
