This　paper　presents　a　novel　robust　control　approach　for　the　attitude　maneuvering　control　of　a　spacecraft　with　flexible　appendages　embedded　with　piezoceramics　as　sensors　and　actuators.　Based　on　the　nonlinear　model　of　flexible　spacecraft,　a　new　attitude　maneuvering　controller　is　derived　to　control　the　attitude　motion　of　spacecraft　by　using　adaptive　sliding　mode　control　technique.　For　actively　suppressing　the　induced　vibration,　positive　position　feedback　(PPF)　compensator　feedback　gain　is　also　designed　for　the　lower　order　modes.　Numerical　simulations　are　performed　to　show　that　both　rotational　attitude　maneuver　and　vibration　suppression　can　be　accomplished　effectively.
