| Summary: | 碩士 === 大同工學院 === 電機工程研究所 === 81 === In this thesis, a digitalized speed regulator of induction
motor is proposed by using indirect field-oriented
method incorporated with space vector PWM technique to
obtain quick response and noise-free operation. In
particular, the PWM waveform are easier to generate with
software according to different switching positions of
space vector, it could enhance the variable speed drive to
smooth current transfer easily and to suppress torque
pulsation. he motor starts and accelerates at stand still
according to By using a TMS320C14 microprocessor to
execute the field-oriented control algorithm and digital PWM
generation, all processing will be accomplished within 250us.
Finally, it is shown that the proposed system has low
distortion sinusoidal current waveform and quick response from
2 to 60 HZ.
