摘要: 本文讨论了一般二阶力学系统的稳定裕度判别准则,阐述了按“系统阻尼”判写系统稳定裕度的不合理性,并从能量的观点出发提出了广义能量的概念及相应的守恒律以及在此基础上以广义能量比率度量系统稳定裕度的原则。

关键词: 广义能量判据, 稳定裕度

Abstract: In this paper, the criterion for the judgment of stability of general mechanical system is discussed, and the calculation result shows that it is unreasonable using "System Dam-ping" for above purpose. The concepts of general energy and the principle of general energy concervation are elaborated in detail, and the ratio of general energy is used as the index to determine thestability margin of system.

Key words: 广义能量判据, 稳定裕度
