Inversion of fuzzy models-practical issues
Dimitar Filev · 2002
This paper deals with some practical issues of the inversion of nonlinear static systems described by fuzzy models. We derive an analytical expression of the derivatives of a fuzzy mapping and we use it in an optimization based inversion algorithm. We discuss some practical aspects of this algorithm, including the inversion of multiple-input, multiple-output (MIMO) fuzzy systems. We also demonstrate how this approach can be used for calculation of the simultaneous solution that follows from two alternative fuzzy models.
