人控交会对接控制方法研究

追踪器上的航天员根据摄像机的图像手动操作手柄完成目标器和追踪器的对接任务,为了减轻航天员负担,提高人控对接成功率,文章提出的思路是姿态控制采用自动控制,使得追踪器姿态和合作目标器姿态保持一致,航天员只负责相对位置控制。文章给出了航天员的相对位置控制策略,并将全系数自适应控制和PID控制方法用于追踪器的姿态控制。仿真结果表明,采用全系数自适应控制进行姿态控制过渡过程时间短、稳态精度高,有利于航天员完成人控对接的任务。

Control Method Research of Space Manual-control Rendezvous and Docking

The pilot on the chaser spacecraft manipulates the stick to dock by the camera- assisted view of the target.In order to release the pilot's pressure and guarantee the success of RVD,the pilot is only in charge of the control of relative position while the chaser's attitude is kept consistent with the target's by automatic control system.The relative position control strategy and method of the pilot are proposed.The all-coefficient adaptive control and PID control Method are applied to the relative attitude control.The result indicates the allcoefficient adaptive control is better to the pilot's relative position control because of its small overshoot and fast slew maneuver.
