在非线性网络响应分析中,采用Volterra级数法可以导出与线性系统传递函数相似的非线性传递函数,能使非线性系统用线性化和系统化方法达到精确分析.文中给出了非线性网络响应的Volterra级数解的连续算式,为解决连续算式计算麻烦的问题,提出用方波脉冲技术处理用Volterra级数表示法描述的非线性网络响应与激励之间关系的一组广义卷积积分的迭加计算,从而得到非线性网络响应求解的Volterra级数解的离散算式.仿真表明该算法求出的非线性网络响应与真实模型曲线十分逼近,证明了它的有效性.
In the nonlinear network response analysis, Volterra series method can be used to derive the nonlinear transfer function similar to the linear system transfer function, and the nonlinear system can be accurately analyzed by means of linearization and systematic method.In this paper, the nonlinear network In order to solve the problem of calculating continuous equations, a set of generalized convolution integrals are proposed to deal with the relationship between the nonlinear network response and excitation described by Volterra series representation The discrete calculation of Volterra series solution to the nonlinear network response is obtained.The simulation results show that the nonlinear network response obtained by this algorithm is very close to the real model curve and its validity is proved.
