Attitude synchronization is a key technology in the capture of tumbling satellites. The inertia ratio of the satellite is a dominant parameter of the motion. Estimation of the inertia ratio of tumbling satellites is thus an important function for a chaser satellite in order to synchronize its attitude motion with the tumbling satellite motion. This paper proposes a new control scheme named “Smooth Reference Model Adaptive Sliding-Mode Control”(SRMASMC) algorithm for attitude tracking maneuvers. The adaptive law installed on the sliding mode control (SMC) algorithm is employed to estimate the inertia ratio of the tumbling satellite. A smooth reference model is introduced to reduce the control torques at the beginning of the tracking maneuver by the SMC method. The attitude tracking performance of the SRMASMC method is evaluated numerically in comparison to a quaternion feedback control method and a SMC method.
