Keywords: hydrostatic secondary control, loading simulator, fuzzy control, friction

A new concept for a load simulator based on the principle of hydrostatic secondary control is put forward. Some control schemas are put forward and related simulation and experiments work is carried out. Especially a fuzzy controller is designed and applied to overcome the friction. Proving there are better control performances. Its advantage is that there is no extraneous torque and energy saving comparing with traditional electric-hydraulic servo control load simulator.
