摘要
提出了一种以灰色系统理论为基础的粗大误差判别方法,该方法对测量数据少或者难于寻求统计规律的测量过程尤为有效,与算术平均滤波法一起使用可以提高数据处理的效率。理论分析和测试结果表明,采用上述的数据处理方法可以有效地提高测量系统的测量精度和测量效率。
This paper presents a new method of deleting the gross error based on the gray system theory. This method is effective when the test data are few or there are no rules of statistics for the test data to follow. Combining with arithmetic mean filtering, this method can enhance the efficiency of the data processing. It is used in the data processing of the stiffness measurement. Theoretical analysis and many tests prove that this method of data processing improves the measuring precision and efficiency.
