【Abstract】 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.更多还原
