摘要

In this Note, new expressions of the equations of relative motion in general Keplerian orbit are presented, both in a rectangular frame and a spherical frame. It is shown, by introducing the virtual potential field, that a simple PD control law without canceling the coupled terms can perform a rendezvous (without directional constraint) in a circular orbit. Control laws for relative position regulation and tracking in Keplerian orbits are also presented. Besides the proposed control laws, one may use various advanced control laws, such as adaptive and/or robust controls which have already been developed for robot manipulators and spacecraft attitude controls, etc. In addition, control law design using the expression in a spherical coordinate can also be a potential future study, because the spherical frame is more compatible with the radar system for spacecraft navigation.
