摘　　要：从近两年发表在国际重要学术期刊和会议上的相关学术论文出发,对异步电动机无速度传感器矢量控制策略进行了综述,介绍了近年来国际上无速度传感器控制的策略和新进展:直接计算法、模型参考自适应法、转速观测器法、磁链观测器法、信号注入法、人工智能方法等。阐述了常见转速估计方法,并对以上方法进行了分析比较,指出了各种方法的优缺点和适用范围,并对今后的发展方向提出了建议。Speed sensorless control is one of the hotspots in international AC drive field. In this paper, based on papers from the recent academic journals and academic conferences in the recent two years, the conventional and new strategy for speed sensorlcss vector control of asynchronous motor are summarized. Some frequently-used as direct computing method, speed-estimation methods, such model reference adaptive system, speed observer method, flux linkage observer method, signal injection method, and artificial intelligence method, are introduced and both of their advantages and disadvantages, as well as their application. The fundamentals of the above methods also are discussed. Finally, by comparisons of these strategies, some suggestions for future researches fields are explored.
