**4.2. Inputs fuzzification and outputs defuzzification**

In order to examine the fuzzy logic contribution to DTC, the choice of the membership functions number for the fuzzification of flux and torque errors has been repected in this part, i.e two membership functions for ΔФs, because a two level hysteresis controller was utilized to control the stator flux in basic DTC. Whereas three membership functions for the fuzzification of ∆Г because a three level hysteris controller was used to adjust the torque.
