| 摘 要： | 本文首次介绍了一种基于SOPC多核技术的三轴一体化MEMS陀螺数字测控系统。系统通过进行驱动频率闭环、驱动幅度闭环控制,使三只陀螺驱动轴稳定地工作在各自谐振点上且幅度稳定,同时对陀螺敏感轴信号进行解调,实时输出三轴同步的角速度信息。本文采用SOPC多核协调同步、多总线控制、并行计算、数字闭环控制等技术,创新性的构建了单片FPGA内集成多个计算内核的三轴实时并行计算系统,与传统的FPGA+DSP数字控制系统相比显示出小体积、低功耗、低成本、完全可重构、高并行处理能力等优势,同时为今后系统ASIC化打下基础,具有很好的应用前景。

| Abstract: | This dissertation introduces a novel 3-axis MEMS gyro system based on SOPC multi-core technique. Firstly three gyros are made to work on the resonant frequency of their own by means of frequency closed -loop control. Then the amplitudes of the drive signals are set to the desired values by means of amplitude closed-loop control. At the same time the signals in the sense direction are demodulated. At last 3 -axis realtime angular velocity message is transmitted to pc. In this dissertation some topical techni... |
