Abstract

Abstract: Aiming at the control strategy problem of forced flying-around uncontrolled rotating target spacecraft, forced flying-around requires the chaser to have line of sight pointing ability on the uncontrolled rotating target in order to observe it comprehensively in a relatively short time. Firstly, the attitude and motion characteristics of the uncontrolled rotating target are analyzed, the three-dimensional relative motion equations of the chaser and the target are established on the line of sight rotation coordinate system. The problem of chaser flying around the target is turned into a two-dimensional control problem in the instantaneous plane of the line of sight rotation. The sliding mode controller based on fuzzy switching gain adjustment is used to control the movement of targets on the line of sight direction and the vertical line of sight direction. The effectiveness of the proposed control strategy is verified by numerical simulation.

Key words: uncontrolled rotating target, line of sight coordinate system, sliding mode control, instantaneous rotation plane, forced flying-around
