| 摘 要： | 本文提出了受扰线性定常多变量系统“鲁棒”稳定性的一个充分和必要条件。它不仅可用于系统分析中作为“鲁棒”稳定性判据，而且也为“鲁棒”稳定系统的综合提供设计依据。它特别适用于参数变化范围较大的控制对象的综合设计。设计程序包括选择合适的名义设计参数，确定闭环系统的主极点以及检验高、低频稳定性等。

| Abstract: | In this paper, necessary and sufficient conditions are found for the stability of a perturbed linear time invariant multivariable system. The stability criterion is applied to derive guidelines for analysis and synthesis of a robustly stabilizing system, especially for a plant with wide parameter variations. The design procedure includes the selection of a suitable nominal design case for the plant, the determination of the dominant poles for the closed-loop system and the test of the high- and low-frequency stability. |
