BackgroundA lot of efforts have been devoted to the instrument development of simultaneous precision positioning and vibration control for on-orbit optical payloads. However, only series schemes with two active elements which, in fact, are coarse and fine hybrid mechanisms, are researched in despite of adverse impacts on the whole mass and dimensions, control strategy and energy usage. Thus, a new magnetostrictive integrated actuator with just one single active element is proposed to realize those two functions together.MethodsThe detailed scheme is introduced, and the selection of some key parameters are explained first. Then, the explicit expressions are derived and the performances are preliminarily studied by numerical simulations. Finally, a prototype is fabricated, and experimental tests are carried out in view of external disturbances with different frequencies.ConclusionsThe results indicate that the developed actuator can not only actively control the low-frequency disturbances but also can passively suppress the middle-high frequency micro-vibrations during precision positioning.
