Large-scale annular space structure has a wide application prospect in the field of aerospace, this kind of large space structure often produces low frequency continuous vibration under the influence of space environment, which has great hidden danger to the attitude stability of spacecraft. Aiming at the vibration problem of large spatial ring structure, this paper focuses on the analysis of the in-plane radial vibration of the structure. The annular multi-rigid discrete method is used to decompose and analyze the large structure, establishes the dynamic model of annular multi-rigid structure, and uses the linear quadratic regulator (LQR) control method to realize the in-plane radial vibration control of the structure. The simulation results show that the optimal controller based on LQR method can effectively suppress the vibration of the annular multi-rigid structure in the plane under the external disturbance.
