Advancements in Vibration Control for Space Manipulators: Actuators, Algorithms, and Material Innovations

Vibration control in space manipulators is a critical area of research due to the significant impact vibrations can have on the accuracy and stability of these systems. Vibrations can originate from various sources, including the manipulator's own motion, the flexibility of its links and joints, its lightweight and long-reaching design, interactions with the environment, and the operation of onboard instruments and equipment. These vibrations can compromise the precision of tasks involving physical contact and even cause damage to the manipulator or other spacecraft. Despite the essential role of space manipulators in satellite servicing, debris removal, and planetary exploration, effective methods for mitigating vibration effects remain a pressing challenge. Current studies have made strides in dynamics modeling, controller design, and material selection, yet gaps persist in fully understanding and addressing the complex interplay of factors influencing vibration control.

This Research Topic aims to explore recent advancements and challenges in the vibration control of space manipulators using different types of actuators, materials, and structures.
