Attitude and Orbit Control for Closely Observing Attitude-Dodging Target

Huang, Xuan / Zhang, Jin / Zhang, Hanyu / Liu, Yuanhe

Aiming at the situation that the non-cooperative spacecraft keeps the specific surface facing away from the active spacecraft through attitude dodging, the six-degree-of-freedom (6-DOF) attitude and orbit control of the active spacecraft for proximity observation is studied. Based on the relative orbit and attitude dynamics model, an orbit maneuver strategy is proposed, which uses the target's control time delay to fly around the target first at an accelerated angular rate and then at a constant angular rate. Then the desired attitude of the active spacecraft is designed, so as to realize continuous tracking observation of the specific surface of the target. A 6-DOF fly-around-observation hyperbolic-tangent sliding mode controller (HTSMC) considering unknown bounded disturbances is designed, and the stability of the HTSMC is proven. The simulations indicate that the fly-around observation strategy is reasonable and feasible, and the HTSMC has a short convergence time and high control accuracy.
