基于相空间重构的GMDH方法在复杂机械系统状态预测中的应用

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

摘要: 把数据处理的组合法(GMDH)与相空间理论相结合,提出了基于相空间重构的GMDH方法,并且把它应用于复杂机械系统的状态预测.预测和测试矿用汽车发动机曲轴箱窜气压力值证明,采用该方法所得的预测结果比较理想.

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.
