Abstract:According to the reduced order model of induction motor,a model reference adaptive speed identification algorithm was obtained from the equations of motor stator voltages and currents. An improved MRAS model was built with variable parameters. The detailed simulation researches were tested on the speed-sensorless vector control. The simulation results show that this improved MRAS speed identification model has satisfied identification precision and dynamic performance.
Keywords:induction motor   vector control   speed-sensorless   model reference adaptive system
