以时延条件下的地球轨道遥操作交会对接为背景,针对遥操作交会对接中时延引起的控制系统不稳定问题,开展了交会平移靠拢段的控制策略研究,在基于C-W方程的预测显示模型基础上,设计了平移靠拢段纵向速度曲线控制及横向位置-速度的相平面控制算法. 仿真表明,该方法能有效克服大时延影响,具有较好控制效果,且算法简单可靠,易于工程实现.

Based on the problem of ground-based teleoperation rendezvous and docking in earth orbit with time delay,this paperfocused on the delay-induced instability of control system on teleoperation rendezvous and docking. The strategy of orbit control in the final approach phase was studied. A predictive model was established based on the Clohessy-Wiltshire equations. The longitudinal veloci-ty control algorithm and transverse position-velocity control algorithms were proposed based on the previous predictive model. Simulation results show that the control method is effective in alleviating the influence of time delay and the success probability is improved. The algorithm is proved to be simple and reliable, and can be easily implemented in engineering.
