Abstract EN
Among all control methods for induction motor drives, Direct Torque Control (DTC) seems to be particularly interesting being independent of machine rotor parameters and requiring no speed or position sensors.
The DTC scheme is characterized by the absence of PI regulators, coordinate transformations, current regulators and PWM signals generators.
In spite of its simplicity, DTC allows a good torque control in steady state and transient operating conditions to be obtained.
However, the presence of hysterics controllers for flux and torque could determine torque and current ripple and variable switching frequency operation for the voltage source inverter.
This paper is aimed to analyze DTC principles, and the problems related to its implementation, especially the torque ripple and the possible improvements to reduce this torque ripple by using a proposed fuzzy based duty cycle controller.
The effectiveness of the duty ratio method was verified by simulation using Matlab / Simulink software package.
The results are compared with that of the traditional DTC models.
