ABSTRACT = {In this paper, a hybrid passive/active vibration (HPAV) controller of a loosely
connected spacecraft consisting of a servicing satellite, a target and an X-shape structure
isolator is first proposed to suppress vibrations of the system when subjected to the
impulsive external excitations during the on-orbit missions. The passive dynamic response
of the combined system can be adjusted appropriately to achieve the desired vibration
isolation performance by tuning the structural parameters of the bio-inspired X-shape
structure. Moreover, the adaptive control design through dynamic scaling technique is
selected as the active component to maintain high vibration isolation performance in the
presence of parameter uncertainties such as mass of the satellite platform, the damping
and rotation friction coefficients of the X-shape structure. Compared with the pure
passive system and the traditional spring-mass-damper (SMD) isolator, the HPAV strategy
witnesses lower transmissibility, smaller vibration amplitude and higher convergence
rate when subjected to the post-capture impact. Numerical simulations demonstrate the
feasibility and validity of the proposed hybrid control scheme in suppressing vibrations of
the free-floating spacecraft.},
