Servicer is required to fast attitude capture after capturing/releasing target. Considering the variable model and nonzero initial angular rate, the paper presents a model independent control law to realize the attitude capture by a move-to-rest eigenaxis rotation. The law adopts the attitude information and the deviation information of eigenaxis to enable the servicer to perform attitude capture rapidly within constraints of slew rate and control torque by the cascade-saturation control logic. Finally, a simulation is also illustrated, and the results prove that the law has validity and reliability.
