基于相空間重構的GMDH方法在復雜機械系統狀態預測中的應用

Condition Prediction of Complex Mechanical System with GMDH Based on the Reconstruction of Phase Space

摘要: 把數據處理的組合法(GMDH)與相空間理論相結合,提出了基于相空間重構的GMDH方法,并且把它應用于復雜機械系統的狀態預測.預測和測試礦用汽車發動機曲軸箱竄氣壓力值證明,采用該方法所得的預測結果比較理想.

Abstract: A method of combining Group Method of Data Handling with phase space theory to predict the condition of complex mechanical system has been built. Compared the tested crankcase pressure of mining truck engine with the predicted results, it has proved tO be an effective method.
