碩士 === 國立臺灣科技大學 === 機械工程系 === 105 === With the advance of science and technology, motors are wildly used in industry, daily life and traffic. Nowadays, people are using motor controlled by digital signal rather than those using carbon brush to reduce the instability and cost. Sinusoidal Pulse Width Modulation(SPWM) and Space Vector Pulse Width Modulation(SVPWM) are usually used to control AC motors. For SPWM, we produce sinusoidal power sources whose frequency and magnitude can be tuned. For SVPWM, we consider the inverter and AC motor as a system. The model of SVPWM technique is simpler, and it is easier to take real-time control for MCU. In this thesis, we use SVPWM technique to produce inverter signals in order to control motors. We use control kit from Texas Instruments and AC motor from TECO. Taking no load and lock rotor experiments, given frequency command from 9.6 to 60 Hz, the errors of results are within 15%.
