ABSTRACT:
A method and apparatus for an electro-hydraulic actuator (1) having mechanical feedback provide closed loop control with a high degree of accuracy. The electro-hydraulic actuator (1) includes a current versus load generator (10), a single-stage servomechanism (20, 21, 22, 23), and a device (24, 25, 40, 41) for providing a mechanical feedback force for offsetting an input force (Fsol) of the current versus load generator (10).
