Improved State Variables Analysis and Its Computer Realization

改进状态变量法运用了等效电路的概念,建立了改进的状态向量方程,该方程中包含了确定状态向量初始值的约束条件并同时自动建立了初始值计算公式.这简化了初始值的计算工作,因此克服了传统的状态变量法在这方面的缺陷.该计算公式适用于任意激励、特别是冲激激励作用下的动态电路初始值的计算,简单实用.在此基础上,给出了改进状态变量法的计算机实现方法,其计算程序是一套系统完整的状态变量法分析程序,具有很强的电路适用性.

The improved state variables analysis uses the concept of equivalent circuit and establishes the improved state vector equations, these equations, contain the restraint conditions of determining the initial values of the state vectors, at the same time, the calculation formulas of initial value is established automatically. It simplifies the calculation of initial value, and thus overcomes the imperfection of classical state variables analysis at this point. These formulas are suited to the calculation of the initial values in dynamic circuits at any excitation, particularly at impulse excitation, and are simple and practical. On this basis, the realization of the analysis on a computer is given and the calculation program is a set of systematic and complete analytical program and has a powerful circuit applicability.
