摘要：Field oriented control (FOC) and direct torque control (DTC), also called vector control, aremost famous control methods in high-performance motor applications. If we want to specify thebasic handicaps of both methods: the FOC has parameter dependence while the DTC has hightorque ripples. This paper proposes a new adaptive bandwidth approach to reduce torqueripples in DTC controlled induction motor drives. With the proposed method, instead of fixedbandwidth, adaptive bandwidth approach is investigated in hysteresis controllers on the DTCmethod. Both the conventional DTC(C-DTC) method and adaptive bandwidth DTC (AB-DTC)for induction motor are simulated in MATLAB/SIMULINK and the results are presented anddiscussed to verify the proposed control. The comparisons have shown that, torque ripples havebeen reduced remarkably with the proposed AB-DTC method.
