Error Analysis and Modification of Inverse Simulation for Manually Controlled Rendezvous and Docking

AbstractBased on the characteristics of manually controlled rendezvous and docking, this paper proposes a novel discrete inverse-simulation method for investigating handling qualities. The proposed method was verified by teleoperation console experiments. The steady-state error and stability were analyzed using Z-domain criteria and verified by theoretical simulation. Furthermore, to reduce the high-frequency oscillations caused by the observed errors, the inverse-simulation method was modified by combining it with adaptive predicted-threshold filtering. The simulation results indicate that the modified inverse strategy can be used to dampen the oscillations and better reproduce maneuvers.
