Reviews on symplectic method for dynamics and control of ultra-large space structures
A ultra-large spacecraft is a significant space infrastructure for the exploration and utilization of space resources,and also an important aerospace equipment to achieve the goal of becoming a powerful space nation.With its ultra-large size,ultra-flexible structure,and ultra-low fundamental frequency,ultra-large spacecrafts present new challenges in terms of dynamic modeling,numerical analysis,precise attitude control,low-frequency vibration suppression,and wave characteristics adjustment.This paper introduces our research progress for the above problems based on symplectic methods,including on-orbit coupling dynamics and attitude control,wave analysis and control,design of deployable space structures,and variable-stiffness active control methods.
