摘　　要：采用方波脉冲函数变换,将具有统一形式数学模型的非线性动态网络在时域内响应的Volterra级数解的递推算式变换成方波域内的数值递推算式。此法不仅为非线性模拟电路故障信号仿真算法的实现提供了新的方法,而且为该类非线性网络的分析计算开辟了新的途径。文中给出了仿真算法和非线性动态电路故障信号仿真实例,在弱非线性情况下,本例取Volterra级数的阶N=3,可得到相当精确的结果。By combining Block-Pluse Function Transform with recursive calculation formulas of Volterra series solution of mathematical model of nonlinear analog dynamic circuit, a set of numerical recursive calculation formulas is obtained in the paper. This method can be used for simulating and analyzing the fault signals of nonlinear networks which have a given type of unified mathematical model. A simulating example of fault signal for nonlinear circuit and simulation algorithm are also given. Under weak nonlinear situation, it is enough to take three or four orders for exact results.This algorithm provides a new way for simulating and analyzing the fault signal of nonlinear analog dynamic circuits.
