Therefore, the ANFIS model provides predictions with high accuracy, which proves to be a new approach for estimation of permeability and inertial coefficient.

The rapidity of convergence was improved with introducing dynamic step size and inertial coefficient, and the prediction precision was improved with introducing modified prediction model.

The inertial object with uncertain coefficient is a class of difficult object, in this paper, an method of control based on the experiment rule for the Si-Mo Furnace is developed.
