文摘This article presents the synthesis of a dynamic output feedback controller for a satellite orbital system confronted with uncertainties.The investigated method transforms the closed-loop system,synthesized by the controller,into anα-strictly negative-imaginary system.It utilizes the DC-loop gain condition associated with negative-imaginary systems theory to demonstrate robust stability of the satellite orbital system in the presence of uncertainties.Furthermore,the synthesized negative-imaginary closed-loop system exhibits notable time-domain performance.The numerical simulation outcomes presented in this article validate the investigated synthesis method.
