This paper describes investigations on adaptive vibration control and shape adjustment of truss structures making use of the active member actuator. The actua tor was manufactured in an attempt to achieve these functions by linear actuating. Funda mental characteristics were examined statically and dynamically. Numerical simulations of planar truss model with the configuration of one pair of collocated actuator and sensor shows that a state observer can estimate truncated modes well and the excited vibration can be controlled rapidly.
