摘要
Abstract
The multi-phase permanent magnet synchronous machine (PMSM) has the property of small size, low noise and high power density, so it has been widely used in high-power and low-voltage occasion. Based on the analysis of traditional direct torque control (DTC) models and space vector pulse width modulation (SVPWM) technologies, a fixed switching frequency modified DTC algorithm of five-phase PMSM with multi-objective optimization was proposed, which aims at improving the trajectory of stator flux effectively, reducing torque ripples and low harmonic components of stator currents. The proposed algorithm brings the following benefits: such as fast torque control dynamic response, the fixed switching frequency, the optimization control of torque, stator flux and stator phase currents. Simulation and experimental results show the feasibility and effectiveness of the proposed algorithm.关键词
