GM(1,1)模型在虚拟仪器测量过程控制中的应用

Application of GM(1,1) grey model in measurement process controlling of virtual instrument

虚拟仪器的测量过程控制是保证测量数据有效的重要手段,利用灰色系统GM(1,1)模型对虚拟仪器的测量过程进行控制,由少量数据信息得到未来的预期测量结果,通过与核查标准的测量结果相比较来判别测量过程是否受控.论文给出了测量过程控制判别限、适用灰色系统GM(1,1)模型的条件以及模型精度检验判据.

Measurement process controlling of virtual instrument is an important means to obtain effective measuring data. A new method with grey model of GM （ 1,1 ） has been given to control the measurement process of virtual instrument in this paper. The forecast measurement result estimated with a little information is compared with measuring data to confirm that whether the quality of virtual instrument is controlled. The distinguish limits and conditions of grey model of GM （ 1,1 ） in point as well as the inspection method of model precision were explained. An example shows that this method has high precision, and it is simple and practical.
