Confidential

Graduate Student and Graduate Research Assistant

Responsibilities:

• I designed, manufactured and debugged a prototype controller module for the project of “Design and Implementation of Microcomputer Excitation Controller for Synchronous Generator Based on DSP.” The controller was based on the TI’s DSP TMS320LF2407A. The project originally implemented a research on microcomputer excitation controller based on DSP in China.
• The research project was concerning the design of the whole hardware platform that realizes the computer excitation regulator with DSP. The controller consisted of digital and analog circuit, such as a power supply and reserved power supply module, a data acquisition module, a voltage level matches module, an extension SRAM and FLASH ROM module, a SCI and CAN communication module and a keyboard and LED module. Moreover, I finished several software modules that corresponded to the hardware modules, including a SCI communication module, a CAN communication module, a PWM producing module and a FFT algorithm-realizing module.
• The hardware and software modules all went through serious and logical measurements and trials. The test data were analyzed by using different debug and simulation methods. For example, I compared the data attained from FFT algorithm running in my designing DSP controller with the data attained from the same FFT algorithm running in MATLAB, and analyzed them. I drew data from simultaneous sampling that faithfully recorded the wave information. I emulated the PID Controlling algorithms with MATLAB and attained exact parameter of PID. The PWM pulse and CAN data from communication proved the feasibility of the relevant hardware and software design. They proved the validity of the project design.
