  In this paper,firstly,to overcome the shortcoming of traditional ARX model, a
new operator between an interval number and a real matrix is defined, and then
it is applied to the traditional ARX model to get a new type of structure
interval ARX model that can deal with interval data, which is defined as
interval ARX model (IARX). Secondly,the IARX model is applied to moving
pattern-based modeling. Finally,to verify the validity of the proposed modeling
method,it is applied to a sintering process. The simulation results show the
moving pattern-based modeling using the new type of interval ARX model is
robust to variation in parameters of the model, and the performance of the
modeling using the proposed IARX is superior to that of the previous work.
