基于参考轨迹的失效卫星相对位姿建模与控制
Modeling and Control of Relative Position and Attitude of Failed Satellite Based on Reference Trajectory
摘要
Abstract
The super-close distance perambulation of the chaser satellite with respect to the non-cooperative satellite is taken as the background. Research is conducted on the modeling and control of the relative position and attitude for the non-cooperative failed satellite based on the reference trajectory. According to the fixed-axis, slowly rotating characteristics of the non-cooperative satellite, an interest field is determined on the surface of the failed satellite, and the reference frame and interest frame are established for the model design of the relative position and attitude. It’s convenient for the real-time calculation of the reference trajectory instruction. According to Hill equation and attitude dynamic model, an approximate coupling relative position and attitude dynamic model is proposed based on the reference point of the non-cooperative target. On this basis, the relative position and attitude coupled control method is designed, and the simulation is verified. The simulation analysis has showed that the proposed relative position and attitude dynamic model based on the reference trajectory is simple and valid, and the designed coupled control method has high control precision whose control precision of relative position is 0.1 meter and relative attitude is 0.15 degree.关键词
