摘　　要：阐述了异步电机转速估计基本原理,指出了常规方法所存在的问题。提出了一种基于模型参考自适应算法的无速度传感器技术,在这基础之上,进一步提出了一种新的自适应转速估计方法,仿真结果证实了这种新方法的正确性和可行性。The fundamental principle of speed identification for induction motors is introduced. The drawbacks of the usual method of speed identification is pointed out. In order to solve these problems, the theroy of MRAS and its application of speed sensorless are proposed. Derived from MRAS, a new adaptive method of speed identification is also put forward. Simulation results have proved that this new technology is correct and practical.

关 键 词：自适应算法 无速度传感器技术 异步电机 自适应转速估计
