Part of the Advances in Soft Computing book series (AINSC, volume 19)


The Takagi-Sugeno model is very popular in fuzzy logic area. It can approximate different functions and physical processes. However, it is known that the model has one inconvenience. If simple triangular or trapezoidal membership functions are used for fuzzy sets then in intermediate area, described example by two fuzzy sets (conclusions of two rules) and two approximate functions used in these rules, the model can not approximate the process well. In the paper simple modification of the model is presented as one giving very good result.
