基于Huston多体系统理论的转台定位误差建模分析

Modeling and Analysis of Positioning Error for Turntable Based on Huston Multibody Theory

首先概括介绍了Huston多体系统理论,然后利用此理论建立了转台方位和俯仰定位误差模型,最后利用建立的误差模型分析了各项误差对转台定位误差的影响。此模型计算转台定位误差比逐步投影法和坐标变换法更加规范和易于计算机编程计算,为通过计算机对转台定位误差进行补偿提供了可操作的具体方法。

Firstly,the article briefly introduces the Huston multi-body system theory.Secondly,this article presents the error models of orientation positioning error and pitch positioning error model.At last,the authors analyse the effect of each single error on turntable positioning error.The result reveals that the Huston multibody system theory is better than projection method and coordinate transformation method,which is more standard and easy for computation with programaning.The authors conclude that this study provides operable concrete method for computer aided error compensation.
