摘要

提出了一种新的感应电机无传感器转速估计算法。该算法以瞬时输入的虚功率作为估计技术的基础。该算法简单，需要的参数知识最少。此外，由于基于虚功率，它在低速时不会因定子电阻的影响而出现精度问题。本文概述了该算法，并给出了感应电机驱动系统的仿真和实验结果。

Speed estimation for induction machines using imaginary power

This paper presents a novel algorithm for sensorless speed estimation for induction machines. The algorithm uses the instantaneous imaginary power flowing into the machine as the basis of the estimation technique. The algorithm is simple and requires minimal parameter knowledge. Furthermore, being based on imaginary power, it does not suffer from accuracy problems at low speeds due to the influence of stator resistance. The paper outlines the algorithm and then presents simulation and experimental results on an induction machine drive system.
