摘要
本文探讨了另一种形式的频率稳定性判据。该判据在公式中已经考虑了开环特征方程式的零根和虚根,因此在判别时对它们的存在与否不须要进行任何特殊处理。
This paper offers another crlterion for stability by means of frequency characteristic. In the formula of the criterion, the roots with zero value and roots with imaginary value in the characteristic equation of the openloop system have been taken into consideration and therefore they need no special treatment
