摘要

本文在改进节点法的基础上，利用符号计算和遗传算法，提出了一种确定非线性电路偏置点的方法。对于电路的求解，以部分符号形式写出了修正节点法所对应的方程组。在这些方程的部分符号形式的基础上，生成了一个误差函数，给出了电路的最小解。本文给出了几个迭代求解不收敛的电路实例。这些电路可以用详细的方法求解。

Analysis of direct current nonlinear electrical circuits by means of symbolic computation and genetic algorithms

The paper presents a method for the determination of the bias point of nonlinear electrical circuits, based on the modified nodal method, by utilization of symbolic computation and genetic algorithms. For the solving of the circuit it is written the equations system corresponding to the modified nodal method in a partial symbolic form. On the basis of the partial symbolic form of these equations an error function is generated which gives the circuit solution by minimization. In the paper are presented a few examples of circuits, for which iterative solving is not convergent. These circuits could be solved by means of the elaborated method.
