Application of grey theory in the correction of the identification parameters of the prediction model of dynamic measurement errors

摘要

In this paper, on the basis of modern error-correction technology the short-term prediction model of dynamic measurement errors is researched by grey-system theory This paper is emphasized on the problem of the identification and correction of the model's parameters. Furthermore, a long gating measuring system is taken as the object, and it's dynamic measuring errors as the practical data. The correcting methods of identification parameters that affect the accuracy of the model during predicting are discussed, thus, the measurement accuracy is improved. Key words: modem technology of error correction, Grey-model of error prediction, the correction of identification parameters of the model, combined model.
