摘要

这项工作提出了一种选择由矩阵变换器(MC)产生的电压空间矢量的方法，用于异步电机直接转矩控制(DTC)的实现，以改善机器的动态响应并限制启动电流。该选择策略选择了减小电磁转矩脉动和提高MC输入功率因数的空间矢量。最后的空间矢量选择考虑了优化的DTC选择表、最小化变换器输入位移因子所需的MC电流矢量和最小化转矩脉动函数。利用系统模型进行了仿真，结果表明了该方法的有效性

Induction Motor Direct Torque Control Using Matrix Converters

This work presents an approach to the selection of the voltage space vector produced by a matrix converter (MC) used in the implementation of an induction motor direct torque control (DTC) in order to improve the machine's dynamic response and limit the start-up currents. The selection strategy chooses the space vectors that reduce generated electromagnetic torque ripple and improve the MC input power factor. Final space vector selection is performed taking into account the optimised DTC selection table, the MC current vector required to minimise the converter input displacement factor, and the torque ripple minimisation function. The simulation results, obtained using a system model, show the method efficiency
