In order to better meet the future high precision task requirements, the DFP(Disturbance-Free Payload) spacecraft composed of non-contact PM(Payload Module)and SM(Support Module)is taken as the object to study the relative motion dynamics modeling and control between the two modules and verify the system vibration isolation performance. Firstly, the force and torque expressions of the two modules are derived by simplifying the configuration and analyzing the stress. In view of that couple effect, the relative motion dynamics equations between two modules of DFP spacecraft with high model accuracy, and simple and uniform format are established with the dual quaternions. Based on this, the PD control law is designed, and the relative motion of PM and SM could meet DFP spacecraft working requirements when the measurability of control quantity and the measurement error of sensors were taken into account. Simulation results verify the advantage of vibration isolation and attitude maneuverability of DFP spacecraft.

Relative Motion Dynamics

Parametric optimization study is carried out on performance measure for assessing the benefits of relevant ground-track parameters and Instantaneous Overlap Area (IOA) in near earth and near-equatorial twin-satellite formation flying to explore its potential as space platform oriented towards Tropical Resources and Environment Monitoring mission. The present study also emphasizes two aspects: the dynamics of relative motion of multiple spacecrafts and the desirable ground tracks such missions. Relative motion dynamics incorporating Clohessy-Wiltshire Equation for circular orbits is used as a reference. The performance metric is synthesized as a tradeoff between exact definition and intuitive judgment.
