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 used in fuzzy logic together with duty ratio control and DTC for a torque commands of 2.4Wb for 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 DTC while fuzzy logic together with duty ratio control, the ripple was minimized more 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..

Figure 4.2 Result for flux linkage in fuzzy logic with duty ratio and DTC were used.
In the analysis, the data in the table were used. The torque response of the motor using ordinary DTC and fuzzy logic with duty ratio control for a torque flux in fuzzy logic with duty ratio control and DTC torque command of 2.4Wb with the drive output updated at a rate of 5kHz were used, the ripple generated was 4.67Wb (18-13.33) Wb greater and lesser values with ordinary DTC, while in fuzzy logic with duty ratio control, ripples was reduced further to 0.667b (2.4-1.733)Wb upper and lower values, assumed order response in flux value at starting of each voltage sector were neglected.
