交流电动机微机测试系统的误差分析

The Error Analysis of Micro-Processor-Controlled Testing System of Induction Motors

简要地介绍了ＭＣＳ－５１微机测试系统的组成和功能。然后详细地讨论了量化误差、变送器误差和互感器的比差和角差对系统误差的影响，最后分别用绝对值和法与方和根法对系统误差作了估计。

irst,this paper gave a brief introduction to the structure and function of amicro-processor-controlled testing system.Then there was a detailed discussion about the effects A/D error,Cransducer's error and inductor's error on the system error. Finally,the systemerror was estimated with absolute truth addition method and quadratic mean root mothod.
