相对度一和相对度二系统的负虚状态反馈等价性

Negative Imaginary State Feedback Equivalence for Systems of Relative Degree One and Relative Degree Two

Kanghong Shi, Ian R. Petersen, Igor G. Vladimirov

摘要:

本文给出了相对次数为1或2的线性系统状态反馈等价于负虚系统的充要条件。更确切地说,我们证明了一类线性时不变严格适当的系统,这样的系统可以呈现最小和NI使用全状态反馈当且仅当它是可控的和弱最小相位。还提供了一个强严格的负虚部状态反馈等价结果。NI状态反馈等价的结果,然后应用于一个不确定系统的鲁棒镇定问题的严格负虚不确定性。

英文摘要:

This paper presents necessary and sufficient conditions under which a linear system of relative degree either one or two is state feedback equivalent to a negative imaginary (NI) system. More precisely, we show for a class of linear time-invariant strictly proper systems, that such a system can be rendered minimal and NI using full state feedback if and only if it is controllable and weakly minimum phase. A strongly strict negative imaginary state feedback equivalence result is also provided. The NI state feedback equivalence result is then applied in a robust stabilization problem for an uncertain system with a strictly negative imaginary uncertainty.
