研究目标航天器存在机动的情况下追踪航天器与目标航天器的交会问题.只利用两航天器之间的相对位置测量信息,考虑目标机动、外部干扰以及状态耦合,提出一种改进的特征压缩方式并建立相应的解耦特征模型,基于该特征模型设计解耦的自适应控制方法实现追踪航天器与机动目标航天器的交会.仿真结果验证了算法的有效性,并表明其优于传统的PD控制方法.
This paper discusses the problem of rendezvous with a maneuver target spacecraft. Considering the maneuvers of the target spacecraft,as well as the external disturbance forces and the coupled states,a modified compress method is proposed and applied to establish the decoupled characteristic model based on the measurements of relative position. Then,a decoupled adaptive control method based on the characteristic model is presented to achieve the rendezvous of the two spacecraft. Finally,the simulation results demonstrate the effectiveness of the proposed method,and indicate that the method is better than the traditional PD control.
