Figure 4.2 Result for flux linkage when fuzzy logic with duty ratio and DTC were used.
In the analysis, the data in table above were used. The flux behavior of the motor using ordinary DTC and fuzzy logic with duty ratio control for a torque command of 2.4Wb with an output drive 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 fuzzy logic with duty ratio control, the ripple was 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..
