Direct Torque Control of Brushless DC Drives With Reduced Torque Ripple

Yuchen Liu, Z. Q. Zhu, D. Howe

Open publisher page 281 citations

Abstract

The application of direct torque control (DTC) to brushless ac drives has been investigated extensively. This paper describes its application to brushless dc drives, and highlights the essential differences in its implementation, as regards torque estimation and the representation of the inverter voltage space vectors. Simulated and experimental results are presented, and it is shown that, compared with conventional current control, DTC results in reduced torque ripple and a faster dynamic response.
