碩士 === 國立勤益科技大學 === 電機工程系 === 100 === In this thesis, we mainly use the TMS320F2808 Digital Signal Processor (DSP) and Intelligent Power Module (IPM) to the implementation of Permanent Magnet Synchronous Motor (PMSM) drive design. The control software is programmed by C language in TI CCS 3.3 (Code Composer Studio 3.3) console, and most of the data and control results are also shown by it. The inverter to deliver the power to the PMSM is made by IPM module to minimize the board. Speed control signal is from the encoder feedback, and current feedback signals are from two Hall sensors filtered by second-order Low-Pass Filter (LPF). The Space Vector Pulse Width Modulation (SVPWM) strategy is used to convert the 48V DC power supply into AC voltage source to the motor according to the vector control structure. Three digital PI controllers are used to complete the speed and currents control. Finally, experimental results including the performance testing of DSP and the drive system are both given to shown the performance of hardware and software design.
