基于DSP2812的无刷直流电机调速系统设计

Design of Brushless DC Motor Speed Control System Based on DSP2812

介绍了无刷直流电机的基本组成、工作原理和数学模型,以DSP TMS320F2812芯片为核心,完成了控制系统的主电路、控制电路、驱动电路、检测电路和保护电路的硬件设计和主程序及相应的中断服务程序的设计,并给出了样机运行的实验结果。

In this paper,the detaiIs of brushIess DC motor component,fundamentaI principIe and mathematicaI modeI is introduced, the brushIess DC motor speed controI methods are anaIyzed and studied.The motor speed controI system is studied on base of 32-bit fixed-point DSP TMS320F2812.Hardware design incIudes：the overaI scheme of hardware,the main circuit, controI circuit,driver circuit,protection circuit and the detection circuit.Software design being conducted,the main program and the corresponding interrupt service program are finished.So that,the programs are modified,debug,and transpIant easiIy.
