偏心航天器有限推力姿轨耦合控制
Integrated Orbit and Attitude Control of Spacecraft with Deviated Centroid and Finite Thrust
摘要
Abstract
A finite thrust orbit and attitude control scheme is proposed to solve the problem of unadjustable orbit control thrust with large misalignment for a spacecraft with deviated centroid.The proposed orbit control scheme can control multiple orbit elements at the same time.The problem of unadjustable orbit control thrust is solved by taking the thrust angle as the control input of orbit control.When designing the attitude control strategy to track the de-sired attitude of orbit control,the large interference torque caused by the thrust misalignment is considered.To solve the problem of large disturbance,the traditional asymptotically stable attitude control law is improved.The coupling relationship of three-axis attitude is used to counteract the influence of interference torque.The effective-ness of the orbit and attitude control strategy is verified by numerical simulation.关键词
