摘要

提出了一种考虑铁芯损耗的异步电动机高效高响应无速度传感器矢量控制方法，并对系统性能进行了讨论。提出的矢量控制系统由考虑铁心损耗的速度自适应转子磁链观测器和补偿铁心损耗影响的直接磁场定向控制方案组成。仿真和实验结果表明，该系统在转子磁链发生变化的情况下也能估计出电机转速。

A speed sensorless vector control of induction motor operating at high efficiency taking core loss into account

This paper proposes a speed-sensorless vector control method for an induction motor operating at high efficiency and high response, in which core loss is taken into account, and discusses the system's performance. The proposed vector control system consists of a speed-adaptive rotor-flux observer which takes core loss into account and employs a direct-field-oriented control scheme which compensates for the influence of core loss. On the basis of simulation and experimental results, the authors show that the proposed system can estimate motor speed even when the rotor flux is changed.
