　　Design of Permanent Magnetic BLDC Control System Based on Infineon XC167CI MCU
　　Permanent magnetic brushless DC motor is a high-tech production with mechanical, electrical and electronic technology, and has the specialties of simple structure, reliable running and long useful life and is used widely in the industry. With the rapid development of modern industry, the requirement to the performance of BLDCM control system is more and more high. Ball Neodymium Magnets So, it is very significant to research such a control system with quick response, powerful regulation capability and high precision.This essay introduces the components of a whole BLDCM control system and its research direction, INFINEON XC167CI 16-bit high performance MCU, and types of BLDCM. Then, analyses the running principle of BLDCM, builds mathematical model, expatiates the torque-ripple and how to lighten it in detail.In this essay, dual closed loop BLDCM control system based on INFINEON XC167CI MCU is designed and implemented. The BLDCM is controlled by PWM mode. The control system with dual closed loop digital PI regulators has good performances in http://www.chinamagnets.biz dynamic and static states. The serial communication between INFINEON XC167CI MCU and LCD display and keyboard setting module makes it possible that the information of the control system can be transmitted between control system and people, which gives convenience for the debugging of the control system, and makes the parameters of the control system displayed real-time.In the end of this essay, analyses the result of experiments based on the waveform collected, and summarized and expected the control system designed and implemented in this essay.From this essay, we can tell that the INFINEON XC167CI MCU has very high performance, and the control system based on it also works reliably. The result of the experiments shows the proposed control solution is feasible, which provides the basis and useful reference for later research.
