一类有静差系统的结构特征

STRUCTURAL CHARACTERISTIC OF A KIND OF SYSTEMS WITH STEADY ERRORS

中文摘要

      通过分析惯性导航系统初始对准方案的静差特性发现，实际工程中存在着这样一类系统，无论为它设计什么样的动态补偿器，其被调节量总是有静差的。且其静差只依赖开环系统的结构参数，而与动态补偿器的结构及其参数的选择无关。我们称这类系统为有差系统。本文分析了有差系统的结构特征，并且给出了通过开环结果参数计算静差的公式。

英文摘要

      From the steady error analysis of the initial alignment of an inertia navigation system, we discovered that there exists a kind of system with steadY errors. In such a system, no matter how to design the dynamic compensator for the system, in the regulation output of the closed -loop system there always exists the steady errors. The steady errors of regulation output relate only with the structural parameter of the open -loop system but is iudependent of the structure and parameters of the dynamic compensator. We call this kind of systems the systems with steady errors. In this paper the structural characteristic of the open -loop system with steady errors by the stauctural parameters of the open -loop system is given.
