考虑三次谐波抑制的改进型五相永磁电机直接转矩控制
Improved Direct Torque Control of Five-Phase Permanent Magnet Motor Based on Third-Harmonic Suppression
摘要
Abstract
Traditional direct torque control (DTC) has many problems such as high harmonic distortion of phase current and significant ripples both on torque and flux linkage in five-phase permanent magnet motor drive,while the DTC based on space vector modulation technique suffers from the heavy computation and the difficulty of realization and parameter adjustment.To solve these problems,a DTC strategy based on third-harmonic suppression of five-phase permanent magnet motor was proposed in this paper.The proposed strategy fully considered the three dimensional subspace of the five phase motor,which can effectively reduce the ripples of torque and flux and the third harmonic content of phase current while ensuring excellent dynamic performance of the DTC system.Besides,the proposed strategy maintained the original intention of DTC,including the simple operation and concise structure.The simulation and experimental results verify the theoretical analysis of the proposed control strategy.关键词
