| Summary: | 碩士 === 大葉大學 === 機械與自動化工程學系 === 105 === This thesis developed the drive system of BLDC motor based on PICDEM MC LV development board with Microchip dsPIC30F3010 microprocessor. The embedded microprocessor has many built-in functional modules, including PWM, compare, timer, etc. The 3-phase MOSFET bridge was used as the motor drive circuit and 3-phase hall sensing circuit was used to detect the electrical angle of motor shaft. The PWM signal was used to control motor speed to achieve the DC brushless motor drive system. The PI control combined with the feedforward control was applied to the motor closed loop speed control. The UART communication module was used to transmit the actual speed of the motor to PC. The command waveform and the actual speed waveform of the motor were drawn with MATLAB. The hardware and software constructed in this thesis were applied to the speed control of DC brushless motor, and the feasibility of the proposed method was verified by simulation and experiment of various speed control.
