Abstract :
In this paper a modelling of a hybrid actuator is proposed. The hybrid actuator consists of a piezo mechanical structure and a hydraulic ratio displacement. Particular attention is paid to a possible Feed-forward control strategy in combination with feedback control to track a periodic signal. Simulations carried out the suitability of the control approach.
