Finite-Time Output Feedback Attitude Control For Double Tethered Satellite System In Deep Space
PROCEEDINGS OF THE 2019 31ST CHINESE CONTROL AND DECISION CONFERENCE (CCDC 2019)(2019)
摘要
This paper addresses the problem of finite-time output feedback decentralized control of double tethered satellite system (2-TSS) attitude tracking in the presence of external disturbances in deep space. More specifically, the finite-time attitude tracking control law with the reconstructed information achieving from the pseudo-angular velocity filter is proposed in this paper. The significant feature of proposed strategy is that the whole closed-loop control system can be guaranteed theoretically to be finite-time stable by the development of adding a power integrator method, which indicates that the tracking errors for 2-TSS are confronted into a small residual region around origin within finite time. Finally, numerical simulation analysis is presented to validate the effectiveness and feasibility of proposed scheme.
