基于DSP和FPGA的电磁轴承控制器的研究

Research on DSP and FPGA Controller of Active Magnetic Bearing

对以DSP和FPGA组成的磁悬浮轴承(AMB)控制系统进行研究,利用DSP强大的浮点运算特性和丰富的外围模块组成AMB的控制部分,利用FPGA灵活的可编程配置和大量.I/O脚组成AMB的三电平功放部分,DSP和FPGA之间采用自定义的并行通信协议格式进行通讯,提高了数据的传输速度和抗干扰性。该控制系统已成功应用在磁悬浮鼓风机上。

The active magnetic bearing（AMB） control system which composed with DSP and FPGA is studied.The control part of the AMB uses a powerful floating point DSP features and rich peripheral module, and the three-level power amplifier of AMB uses flexible programmable FPGA configuration and a large number of I/O pins.DSP and FPGA are communicated by using the parallel communication protocol format which improve data transmission speed and noise immunity.The control systems are successfully used in AMB.
