摘要：Field oriented control and direct torque control are the most popular methods in highperformance industrial control applications for induction motors. Naturally, the strengths andweaknesses of each control method are available. Therefore, the selection of optimum controlmethod is vitally important for many industrial applications. So, the advantages and thedisadvantages of both control methods have to be well defined. In this paper, a new anddifferent perspective has been presented regarding the comparison of the inverter switchingbehaviours on the FOC and the DTC drivers. For this purpose, the experimental studies havebeen carried out to compare the inverter switching frequencies and torque responses ofinduction motors in the FOC and the DTC systems. The dSPACE 1103 controller board hasbeen programmed with Matlab/Simulink software. As expected, the experimental studies haveshowed that the FOC controlled motors have had a lessened torque ripple. On the other hand,the FOC controlled motor switching frequency has about 75% more than the DTC controlled.
