Research on the Control of Large Flexibility Spacecraft Based on Time-Delay Link

For satellites with low-frequency, strongly coupled flexible attachments, the impact of time-delay links on the stability of the control system is particularly evident [1]. For satellites that need large dynamic maneuver tracking, the impact of time-delay links on the control system's attitude accuracy is particularly evident as well. This paper focuses on the time-delay link in the control of large flexible spacecraft, designs several different control strategies in combination with different on-orbit working condition modes, and ensures the on-orbit attitude accuracy of the spacecraft.
