解非线性电路稳态响应的一种有效算法

本文提供一种计算非线性电路的稳态响应的有效算法,在多频信号激励的强迫振荡电路和耦合振荡电路都可使用。该方法可称为“代换算法”。因为,它每一步的变量都是用残留误差的各个频率分量解关联时不变电路,该电路是用“松弛法”将时变电路转换而来。此算法非常简单而有效,并且可应用于各种非线性电路。

A dfficient algori-hm for solving sterdy-state response of nonlinear chcuit

An efficient algorithm is given for calculating the stead-state response of a nonlinear circuit driven by multi-signals. The algorithm cn be applied in forced oscillation circuit and coupling oscillation circuit. The method is called"substitution algorithm", because the variation at each step is calculated by solving an associated time-invariant sensitivity circuit at each frequency component of the residual error, whose circuit is derived from a"relaxation method". The algorithm is very simple and efficient, and it can be applied to a wide variety of nonlinear circuits.
