| Summary: | 碩士 === 國立台灣工業技術學院 === 電機工程技術研究所 === 85 === This dissertation is concerned with the development of
microprocessor(80196MC)based speed sensorless rotor flux-
oriented control of induction motor. In orderto reduce the
circuit component, the command voltage rather than the
feedbackvoltage is used along with the feedback current of
the induction motor tocalculate the magnitude and position of
the rotor flux for speed estimation. The induction motor speed
control system is composed of a speed controller,two current
controllers, a flux controller, a sinusoidal pulse-width
modulatedinverter, a flux estimator and a speed estimator. A
sliding mode proportional-integral control is proposed for the
speed controller to yield fast response andsmall overshoot.
Simulations and experiments are given to verify the analysisand
the practicality of the system.
