本文利用数字计算机为研究非线性系统提供一个方便的工具。给出了系统各部分的数学模型,设计了通用的FORTRAN计算程序。一般常见的非线性特性,诸如正弦周期函数、磁滞、回差和任意形状的单值函数均可以求解。使用者只需将系统参数、初始态、信号参数按照约定的格式穿成数据带,利用本程序上机计算就可以得到非线性系统的动态解。文中计算和讨论了某雷达天线伺服系统中的搜索转跟踪的截获过程、大失调角的调整过程、齿隙振荡和高阶锁相环的捕捉过程等典型非线性问题。
This article uses digital computers to provide a convenient tool for studying nonlinear systems. The mathematical model of each part of the system is given, and a general FORTRAN calculation program is designed. Commonly used nonlinear characteristics, such as the sine periodic function, hysteresis, hysteresis and arbitrary shape of the single-valued function can be solved. Users only need to put the system parameters, the initial state, the signal parameters in accordance with the agreed format to wear data band, the use of this program on the computer can get the dynamic solution of nonlinear systems. In this paper, typical nonlinear problems, such as acquisition-tracking tracing process, adjustment process of large offset angle, backlash oscillation and high-order phase-locked loop capture, are calculated and discussed in a radar antenna servo system.
