Model-Based Development Method Construction UtilizingMulti-Physics System-Level Modeling and Simulation toward Automatic Docking System Demonstration on HTV-X

Abstract

Rendezvous docking is a key technique for space activities and missions, including in-orbit service and planetary exploration missions. One of the planned missions of the HTV-X, successor to the H-II Transfer Vehicle (HTV), is a demonstration of an automatic docking system. These docking systems need a high level of reliability and safety. However, it is difficult to comprehensively evaluate and verify the systems using only ground tests due to the inability to reproduce the actual operating conditions. Therefore, an efficient and reasonable model-based development method has been constructed to evaluate feasibility and safety in this study.
