A new method of successive approximation and iteration for solving nonlinear transformation of probable moments of 1st and 2nd order of output information is presented under identity condition of two sides of the equation. This method can be used to analyse the nonlinear control system which has a Gaussian stationary random input, either open-loop or close-loop. About 20 typical examples both open-loop and close-loop systems have been analysed and calculated with this new method. Analysing the calculation results, author has found that this method is more accurate than other basic methods presented last 30 years or so which have relative error about 30-60%.Comparing this method with others, a discussion is given at the end.

本文对非线性系统输出的一、二阶概率矩变换式提出一种在两端恒等条件下逐次逼近与迭代的新方法——概率渐近法,它能用来分析正态平稳随机输入下的非线性开环与闭环系统。 在对比与分析了将近30年来许多学者的主要方法的基础上,提出了在一、二阶矩变换式两端恒等与充分考虑高阶项的条件下进行正确逼近的新方法,并引入平均解,从而能较简便地求得比其他方法更精确的一,二次解。 文中分析研究了已有的八种概率分析法——线性化法与传统逼近法等。并用20例开、闭环系统,对各种方法作了分析。作者发现许多方法的相对误差达30—60%或者更大。最后指出了各种方法存在的问题。

A method of digital filter network design using observers is presented. This method consists in providing the required close loop system pole positions, and obtaining a digital filter network satisfying the characteristics of the system; whereas the conventional logarithmic frequency method is based on the open loop logarithmic frequency properties, in which the choice of the network depends on the experience of the designer in making system's properties approach the desired ideal properties by way of engineering graphical curves. The former method depends on digital simulation computation and lays stress on realization of the network design on a digital computer, but the latter method relies on designer's experience and lays stress on physical realization of the network design.State vector and matrix vector representations are used in the numerical program calculation for digital network design through the computer. It makes modification and re-design work easier.

本文介绍利用“观测器”设计数字滤波网络的方法。本方法是先给出系统要求的闭环对象极点位置,然后求得满足系统特性的数字滤波网络;而惯用的对数频率法则是基于系统的开环对数频率特性,凭借设计者的经验选取某个网络,用工程作图法使系统特性去逼近希望的理想特性。显然,前者依赖于数字模拟计算,着重考虑网络的数字计算机实现;而后者则取决于设计者的经验,着重考虑网络的物理实现。 另外,本方法对问题的描述采用了状态表示法和矩阵矢量形式,便于数字网络设计的数值计算程序化,因而也就便于修改设计或跨型号的重新设计。
