School of Information & Mechanical Engineering, Beijing Institute of Graphic Communication , Beijing 102600,China)Abstract Speed sensorless control is one of the hotspots in international AC drive field. Both of the conventional and new strategy for speed sensorless vector control of asynchronous motor in this paper referred from the recent academic journals and academic conferences in the recent two years are summarized. Some frequently-used speed-estimation methods, such as direct computing method, model reference adaptive system, speed observer method, flux observer method，signal injection method, and artificial intelligence method, are introduced and both of their merits and dements ,as well as their application. The paper also discussed the fundamentals of the above methods. Finally, by comparisons of these strategies ,some suggestions for future researches fields are explored.Keywords asynchronous motor; speed sensorless; control strategy1 引言异步电动机因其结构简单、巩固耐用、运行可靠、本钱低、易维护、可适合于大容量调速和工作于恶劣环境等优点，在工业领域得到了广泛的应用。长期以来，人们一直期望将异步电动机应用到高性能调速系统中去。但是，由于异...
