Figure 4.2 Result for flux linkage when fuzzy logic with duty ratio and DTC were used.
In the analysis, the data in table were used. The flux behavior of the motor applying fuzzy logic with duty ratio control and DTC for a torque command of 2.4Wb with an output drive updated at the of rate of 5kHz were used, the ripple flux 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..
