This paper studies the controller design for a spacecraft approaching a tumbling space target in the presence of model uncertainties and dynamic couplings between relative rotation and relative translation. An alternative relative attitude function is selected to measure the magnitude of the relative attitude motion carefully, and robust adaptive controllers are designed for relative attitude and relative position to guarantee a desirable stabilization performance uniformly for the relative motion. The strict Lyapunov analysis is presented to prove the uniformly ultimately boundedness of relative motion errors. The relative attitude controller is directly developed on the special orthogonal group SO(3) to avoid complexities and ambiguities associated with coordinate-dependent attitude representations. Performance of the controlled overall system is demonstrated via a representative numerical example.
