摘要

A limited range of actuators is available for controlling the behaviour of space tethers. Length rate/tension control is used for damping liberations in the tether and movement of the tether attachment point has been proposed for use in re-orienting sub-satellites. Other actuators include electrodynamic effects, chemical propellant thrusters and movement of a mass along the tether. In this paper, length rate/tension control, movement of the attachment point and movement of a mass along the tether are applied to the task of manipulating the tether tip so as to track a target6 payload. By developing control schemes employing each of these actuators, it is shown that: instantaneous rendezvous with the target position and velocity is possible using length rate/tension control; movement of the attachment point has very little impact on this application; full tracking (position and velocity) is possible over an extended range using movement of a mass along the tether. Capture of a payload using these techniques is demonstrated in a simulation environment.
