摘要
TMS320LF2407芯片作为数字信号处理器(DSP)24x系列的新成员,是TMS320C2000TM平台下的一种定点DSP芯片。它在与现存24xDSP控制器芯片代码兼容的同时,具有处理性能更好,外设集成度更高,程序存储器更大,A/D转换速度更快等优点。本文在分析其结构特点的基础上,讨论了永磁同步电机(PMSM)的矢量控制调速系统,给出了PMSM速度控制的软件和硬件实现方法。实验结果表明,采用TMS320LF2407实现电机调速,能够获得良好的跟踪性能和较高的稳态精度,从而提高了电机的控制能力。
The TMS320LF2407 device,a new member of the 24x generation of digital signal processor （DSP） controllers,is a part of the TMS320C2000^TM platform of fixed-point DSPs.While code-compatible with the existing 24x DSP controller devices,the TMS320LF2407 device offers increased processing performance, a higher level of peripheral integration,larger programmer memory and more quick analog-to-digital converter （ADC）.Based on the structure analysis of the TMS320LF2407 device,this paper discusses the PMSM vector control system and gives the hardware and software realization.The experiment result indicates that the system utilizing TMS320LF2407 has better tracking performance and higher steady precision and improved the motor control effect.
