摘要

Active tendon, consisting of a displacement actuator and a collocated force sensor, was first presented by Preumont and his co-workers to attenuate the vibration of large flexible space structures, and the control algorithm adopted by them was integral force feedback. This paper pre-sents a new proportional-integral (PI) force feedback algorithm to achieve larger damping ratios for the structure without the requirement of structure model. Stability of the control system is shown, and simulations of a structure simi-lar to JPL-MPI demonstrate the effectiveness of the proposed algorithm for vibration control of space structures.
