FPGA在永磁同步电动机传动系统中的应用

摘要

A design of the FPGA hardware implement of vibration frequency detection was proposed. Based on this design , the continuous and online monitoring on the torsional vibration of drive system were provided. The division and a-chievement of the main modules were introduced. The computational speed of the design was significantly improved by using the improved FFT and pipeline technology. The design was simulated and validated.%提出一种在FPGA中硬件实现振动频率检测的设计方案.基于该方案,控制系统能够对传动系统中的扭转振动进行连续的在线检测.并详细介绍了主要模块的划分和实现,通过使用改进的FFT算法及流水线技术,显著提高了设计的运算速度.最后对设计进行了系统仿真和验证.
