Research on trajectory planning at the end of auto-docking of launch vehicle fuel connector

摘要

To solve the problem about structural failure owing to impact between valve of launch vehicle and fuel connector. Auto-docking could be described as servo to a random moving target which can be measured, while a linear superposition trajectory planning based on five-order polynomial is proposed. Simulations shows that the relative velocity is significantly reduced, and the security and reliability of auto-docking are both improved.
