Low-complexity Stabilization Control of Combined Spacecraft with an Unknown Captured Object

摘要
This paper investigates a low-complexity prescribed performance control approach for combined spacecraft with an unknown captured object in the presence of external disturbance. First, a prescribed performance function with appropriate parameters is selected for the filtered state variables involving the attitude and angular velocity. Then, a low-complexity robust prescribed performance controller is developed without any priori knowledge of the inertial information of combined spacecraft.This dramatically decreases the complexity of controller design for combined spacecraft with large uncertainty owing to the fact that the tedious identification of inertial property is avoided. Finally, an illustrative example is employed to validate the effectiveness of proposed control approach in terms of stabilizing the combined spacecraft.
