| Abstract: | The 3D dynamics model of the tethered subsatellite in circular orbit is presented for the rendezvous and capture of payloads on the basis of Lagrange equations,which also takes tether mass,centroid drift and mission-related state-controlled constrains into consideration.The end terms of zero velocity rendezvous are derived for the study of nonlinear energy-optimal control of safe capture.For ensuring the adaptability,the optimal control is solved by discretizing the problem based on the Legendre pseudospect... |
