Abstract: To deal with the issues such as complex design, difficult on-orbit expansion, and limited fault-tolerance in active controller of vibration of Large Satellite Solar Panels (LSSP), a distributed vibration control approach, which is suitable for the modular structure, is proposed in this paper. According to the structure characteristics of the panel, the LSSP is firstly divided into different units for control system design, and the dynamic model of each unit oriented towards distributed control is developed. The linear quadratic vibration controller of each unit is then designed using the Kalman filter algorithm. Considering the communication of the measured output of each unit, the final distributed vibration control system applied to the whole LSSP is proposed, and stability of the closed-loop system is analyzed. Simulations are finally conducted to verify the validity of the proposed controllers, and the results demonstrate that scalable distributed controllers can achieve vibration suppression for LSSP, and can provide good fault tolerance.
