Electro-hydrostatic actuators are preferred in the aviation
industry due to their compact design and high energy
efficiency. Unlike conventional hydraulic actuator systems,
electro-hydrostatic actuators are controlled directly by pumps
instead of valves, thereby eliminating energy loss caused by
leakages. However, the pump-controlled actuator design limits
the frequency response performance of electro-hydrostatic
actuators, making the improvement of dynamic performance an
active research area. This study investigates the dynamic
stiffness of electro-hydrostatic actuator and designs PID and
sliding mode controllers through simulation. A test setup,
including an external load, is constructed to validate the
performance of the controllers. The frequency and external load
dependent dynamic stiffness of electro-hydrostatic actuator is
obtained, and the performances of the controllers are compared.
