Figure 4.1 Result for torque error using DTC and fuzzy logic with duty ratio.
Analysis, the data in the table were applied. The torque behavior of the motor using ordinary DTC and fuzzy logic with duty ratio control for a torque command of 0.15Nm with the output drive updated at a rate of 5kHz were used. The flux ripple regained was 0.05wb (0.2-0.15)N-m greater and lesser values

with the only DTC while in fuzzy logic with duty ratio control, the ripple was reduced further to 0.0055Nm (0.025-0.00195)Nm greater and lesser value, assumed under shoot in the torque value at the starting point of each
