There are two methods. Viz., Mamdani-type fuzzyinference system and adaptive neuro-fuzzy inference system (ANFIS). The ANFISarchitecture is shown in Figure 2. The ANFIS is a Sugeno fuzzy model where the final fuzzyinference system is optimized via the artificial NN training the main difference betweenMamdani and Sugeno system is that the Sugeno output membership functions are eitherlinear or constant. Therefore, the Sugeno method is computationally more efficient and thusmore likely to have a faster response. Sugeno can be well suited for modeling non linearsystems by interpolating between multiple linear models (Sivarao et al., 2009).
