| 摘 要： | 对乃奎斯特稳定性判据进行了较深入的研究,指出了原乃奎斯特判据在推导及应用方面的不足,从而推导出乃奎斯特稳定性判据的新公式。借助于此公式,可以明确地判定某线性定常系统是属于渐近稳定,还是临界稳定,还是发散不稳定。本文给出具有代表性的一些例题,说明如何利用稳定性判据新公式判定某一线性定常系统的稳定性。

| Abstract: | This Paper researched ttoroughly the Nyquist stability criterion and deduced a new formula of the criterion. Using this formula, the asympototic stability, the Critical stability or the unstability of a certain linear constant system could be determined. Somo typical examples were given to show how to determine the stability of some systems. |
