- Abstract
This study is focused on the influence of system delay on the operator performance in manual-controlled Rendezvous and Docking (RVD). Twenty-one male volunteers aged 22-40 participated in the experiment which was designed on a simulated RVD system. The factor of delay time had three levels corresponding to 0s,1s,2s. The results show that delay time had obvious effects on the operator performance (p$<$0.05). With delay time increased, success rate decreased, translational deviation and velocity at docking stage (0m), and control time increased. According to the results, system delay has a significant influence on the operator performance in RVD process. Based on the experiment results, critical threshold of delay time in manual-controlled spacecraft RVD will be determined for guiding engineering design.
