摘要
提出了电路变量的平衡解、初期量变和反馈增益的概念。稳定电路或不稳定电路可用电路变量相对于平衡解的初期量变趋势来解释,而由反馈增益加以判断。导出了两个基本方程和一些系数行列式定理,其中一个方程用于求解反馈增益,两个判别式定理用于判断反馈增益的取值界限。最后讨论了电阻电路非理想模型和含电容、电感电路的稳定性问题。为了列写电路方程,还提出了电路的独立回路分析法和独立闭面分析法。
The concepts of equilibrium solution, initial variation and feedback gain of circuit variables are introduced. A stable or unstable circuit can be explained with the tendency of initial variation of circuit variables relative to the equilibrium solution, and can be discriminated on the feedback gain. The fundamental equations and some coeffi cient determinant theorems are derived, one equation being used for solving the feedback gain,two discrimination theorems being used for determining the value bound of the feedback gain. Further, the stability of non ideal models of resistance circuits and circuits with capacitors and inductors are discussed. In order to compile the circuit equations, independent loop method and independent closed surface method on circuits are presented.
