Improved GMDH and Its Application
An improved GMDH(group method of data handling)algorithm-GMDH plus model structural optimization was put forward. The variables were self-organized by group and some weak effect was removed to optimize the model structure in the algorithm. When the algorithm was applied into the manufacture of lubricating oil for identifying the mathematical model of the dew axing process of phytol ketone, the acquired model was consistent with the actual operating data. Based on this model, an optimal deduction was made for locating the optimal operating order measured by the biggest absorbing-rate.Theory analysis and simulation result show that the algorithm is effective.
