چکیده
the efficiency of induction motors decreases at light loads. efficiency optimizer control systemsadjust the motor flux value to achieve the best efficiency in a wide range of load variations. reduced fluxoperation has some other benefits such as power factor improvement and torque ripple reduction. the latter isan important issue in a direct torque controlled induction motor drive. in this paper, the effect of fluxreference value on the torque ripple of a direct torque controlled induction motor is analyzed. the effect offlux value on torque ripple in a wide range of speed variations is investigated. simulation and theexperimental results presented justify the validity of the theoretical analysis about torque ripple.

In conventional direct torque control (DTC) of induction machines, undesirable flux and torque ripples are produced. These occur since non of the selected inverter's voltage vectors are able to generate the exact voltage required to produce the desired changes in the electromagnetic torque and stator flux linkage in most of the switching instances. In addition, when direct torque control is imp...
