摘要

本文提出了一种新的矢量控制异步电动机的动态过调制策略，并与传统方案进行了分析比较。该方案通过同时考虑逆变器电压边界和感应电机电流动态，对逆变器输出电压进行分配，使同步d轴电压在参考电压超过六边形边界时成比例降低。因此，矢量控制异步电动机的d轴电流在过调制区减小，保证了控制电压裕度，提高了转矩控制的动态性能。仿真和实验结果表明，该方案比传统方案有明显的改进。

A new dynamic overmodulation strategy for high performance torque control of induction motor

In this paper, a new dynamic overmodulation strategy is proposed for vector-controlled induction motor drive, and a comparison study with conventional schemes is described in an analytical manner. By considering voltage boundary of inverter and current dynamics of induction motor simultaneously, the proposed overmodulation scheme allocates the output voltage of the inverter so that synchronous d-axis voltage is diminished in proportion as reference voltage exceeds hexagon boundary. As a result, d-axis current of vector-controlled induction motor is decreased in the overmodulation region, which secures the control voltage margin and improves the dynamic performance of torque control. The conspicuous improvement of the proposed scheme over conventional ones is observed in both simulated and experimental results.
