模糊方法在间接测量中的应用

The Application of Fuzzy Method in Indirect Measurement

在实际系统中,往往需要利用间接测量建立数学模型,确定一些无法直接测量的变量。将直接被测量和间接被测量都被看作是模糊数。利用模糊方法对间接测量进行处理,在遵循GU M的原则下,利用模糊数学的扩展原理进行误差合成和测量结果的合成,计算间接测量的结果。通过实例证明,该方法是可行的。

In practice,some variables can be not measured directly,it can measure other variables to calculate the variables by the relationship among them.The direct and indirect measureds are treated as fuzzy numbers,the calculation is accomplished by the propagation principle.The method is illustrated by an example,it can be proved that the method is useful.
