Improved Direct Torque Control Method for Dual-Three-Phase Permanent-Magnet Synchronous Machines with Back-EMF Harmonics
IEEE Transactions on Industrial Electronics(2021)
摘要
In this article, we propose a novel switching-table-based direct torque control (ST-DTC) method to eliminate the current harmonics in dual-three-phase permanent-magnet synchronous machines due to the back electromotive force (back EMF) harmonics and voltage vector selection. By employing a novel space voltage vector selection strategy and the optimal action time for different groups of vectors, a ...
