| Summary: | 碩士 === 清雲科技大學 === 電機工程所 === 100 === This paper proposes a model reference adaptive system(MRAS) utilizing the reactive power for the design of a speed estimator for induction motor drives. Slection of instantaneous reactive power in the reference model makes it completely free from the machine parameters. On the other hand, the use of steady state reactive power in the adjustable model eliminates derivative terms from the same. Then a adaptive mechanism is developed to estimate the rotor speed for the implementation of speed sensorless induction motor control system. In addition, a driving technology which based on voltage space vector direct torgue control(VSVDTC) and sliding mode control(SMC) is used to reduce the ripple on speed and torgue wavefroms. Finally, computer simulation and experimental results have been presented to confirm the effectiveness of the proposed method.
