摘要

这篇文章介绍了为一个具有不确定性的卫星轨道系统合成动态输出反馈控制器的方法。所研究的方法将控制器合成的闭环系统转换为严格意义上的负（α）虚系统。它利用与负-虚系统理论相关的直流环增益条件，证明了卫星轨道系统在存在不确定性时的稳健稳定性。此外，合成的负-虚闭环系统还具有显著的时域性能。本文介绍的数值模拟结果验证了所研究的合成方法。

Dynamic output feedback control strategy for a satellite orbital model within negative-imaginary systems theory framework

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 an \(\alpha \)-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.
