Qualitative Modeling For Magnetization Curve, Pei-Hwa Huang, Yu-Shuo Chang

Journal of Marine Science and Technology

This paper studies the derivation of a qualitative description for the magnetization curve of saturable magnetic materials. From a set of numerical input-output data, a fuzzy model, which is a collection of fuzzy IF-THEN rules for describing the studied system, is first constructed for the magnetization curve. A procedure consisting of a fuzzy clustering method and a rule processing algorithm is then employed for processing the constructed fuzzy modeling rules to extract the qualitative properties of the curve. The proposed approach is objective in that it can yield the system qualitative features without domain experts’ knowledge. An example is demonstrated …
