GMDH－EPTSV建模方法及其应用

MODELLING METHOD OF GMDH-EPTSV AND ITS APPLICATION

对于多变量非线性系统，根据控制理论中的自组织原理，提出了改进的主成分分析双向量选择的数据处理组合方法，简称ＣＭＤＨ－ＥＰＴＳＶ方法建立了合成氨系统的数学模型，该方法有较好的模型精度和计算稳定性。

For the multiple variables nonlinear system, according to the principle of selforgnization in control theory,we advance an improved GMDH algorithm with the principal component two-way selection variables (GMDH- EPTSV ) to establish the model for the synthetic ammonia system. GMDH-EPTSV method has a better result and better model accuracy and calculation stability.
