Multi-Axis Selective Decoupling Framework for Free-Floating Space Manipulators
Daegyun Choi, Donghoon Kim
Free-floating space manipulator systems face operational challenges due to dynamic coupling. While traditional reactionless manipulation eliminates base disturbances, enforcing the…
Constrained Attitude Reorientation Maneuver of Spacecraft based on Path Planning
Daegyun Choi, Donghoon Kim, Henzeh Leeghim
Spacecraft attitude control becomes challenging when light-sensitive instruments must avoid bright objects. This work proposes a path-planning-based spacecraft attitude reorientati…
Genetic Fuzzy System-based Control for Final Approach of Spacecraft Rendezvous and Proximity Operations
Daegyun Choi, Donghoon Kim, Henzeh Leeghim
In-space servicing has been receiving great attention to extend the operation of spacecraft with defective components. This requires rendezvous and proximity operations for a chase…
Genetic Fuzzy System-Based Multi-Robot Coordination for Planetary Missions
Daegyun Choi, Donghoon Kim
This paper proposes a decentralized approach for a multi-robot system (MRS) using a genetic fuzzy system to perform a collaborative object transportation task that minimizes the to…
An Algebraic Method for Optimizing the State, Control, and Terminal State Weight Matrices for Optimal Feedback Control
Daegyun Choi, Donghoon Kim, James D. Turner
The necessary conditions for formulating optimal feedback control algorithms have been known for many years. Free parameters exist in the performance index in the form of state and…
Fuzzy-Based Control Method for Autonomous Spacecraft Inspection with Minimal Fuel Consumption
Daegyun Choi, Donghoon Kim, Henzeh Leeghim
This study explores an energy-efficient control strategy for spacecraft inspection using a fuzzy inference system combined with a bio-inspired optimization technique to incorporate…
Understanding and Utilizing Dynamic Coupling in Free-Floating Space Manipulators for On-Orbit Servicing
Gargi Das, Daegyun Choi, Donghoon Kim
This study proposes a dynamic coupling-informed trajectory optimization algorithm for free-floating space manipulator systems (SMSs). Dynamic coupling between the base and the mani…
Adapting Biological Reflexes for Dynamic Reorientation in Space Manipulator Systems
Daegyun Choi, Alhim Vera, Donghoon Kim
Robotic arms mounted on spacecraft, known as space manipulator systems (SMSs), are critical for enabling on-orbit assembly, satellite servicing, and debris removal. However, contro…
A Study on Effective Initial Guess Finding Method Based on Bézier Curves: Orbit Determination Applications
Daegyun Choi, Sungwook Yang, Henzeh Leeghim +1
In celestial mechanics, proper orbits related to missions are obtained by solving two-point boundary value problems. Since a selection method of initial value affects the convergen…
