2 Simulated result for flux linkage error using DTC and fuzzy logic with duty ratio.In the analysis, the data in the table were used. The behavior of the flux of the motor using ordinary DTC and fuzzy logic with duty ratio control for a torque command of 2.4Wb with an output drive was updated at a rate of 5kHz were used, the flux ripple produced was 4.67Wb (18-13.
33)Wb greater and lesser values with the ordinary DTC while in fuzzy logic with duty ratio control the ripple is minimized to 0.667Wb (2.4-1.
733)Wb higher and lower values, assumed under shoot in the flux value at the starting point of each voltage sector were neglected.
