To deal with the problem of vibration control for large-scale flexible space structure, an detailed distributed vibration control scheme with the switch control method and PD control method improved by fuzzy logic system is proposed in this paper. Firstly, the dynamic model, the actuator model and the multi-subsystem model of a large-scale flexible space structure are established. Then, a distributed control scheme is designed, which installs multiple groups of piezoelectric actuators on the

... port truss. The traditional methods and the improved method based on fuzzy logic system are discussed. Through ADAMS-MATLAB co-simulation platform, the effectiveness of the distributed control to suppress the vibration of large-scale flexible space structure in both and directions is verified. The simulation results show that the control precision by the improved method based on fuzzy logic system is better than traditional methods, and the control spillover is not easy to be caused.
