摘要

针对直接转矩控制的船舶电力推进永磁同步电动机（PMSM）在运行时存在较大转矩脉动问题，采用基于十二电压矢量直接转矩控制方法，对电压矢量和磁链空间扇区进行细分，增强了各电压矢量对转矩控制效果，相对于传统的六电压矢量系统，能有效减小约30%~40%的转矩脉动.通过分析给出具体的开关表，并使用Matlab建立仿真模型，验证了该控制方法对减小转矩脉动的有效性.

Abstract

To solve the severe torque ripple problems for direct torque control system of permanent magnet synchronous motor in ship electric propulsion, space voltage vector and magnetic chain fans were subdivided by using twelve voltage vectors in direct torque control, which enhanced the torque control effect of each voltage vector. Compared with traditional six voltage vectors system, the proposed method can effectively reduce about 30%~40% of the torque ripple.Specific switch table was given by analyzing, and simulation model was established with MATLAB. Simulation results verify the effectiveness of the proposed control method in reducing the torque ripple.

Key words： electric propulsion; permanent magnet synchronous motor; direct torque control; twelve voltage vectors; torque ripple
