用灰色关联法处理动态测试数据相关性的研究
On the Correlationship between the Dynamic Test Data Processed with Grey Correlational Analysis
【摘要】 首次将灰色系统理论的关联分析法应用于动态测试数据的研究中,提出了一种新的初值化处理方法.测量实例的计算结果表明,该方法与随机过程相关函数的计算结果相吻合.
【Abstract】 Basing on the grey system theory, a new initializing method of grey correlational analysis is proposed to study the data correlation during dynamic test. As the error is stochastic, all the data in every test sequence are subtracted by the first one in the sequence so as to acquire a new sequence.Then the general grey correlational analysis is used to deal with the error with the macro-environment during the test taken into consideration. Computation results show that the trend of the degree of grey correlation is coincident with that of autocorrelation functions obtained from the stochastic process theory.
