着重对全数字闭环光纤陀螺的信号处理方法进行了详细的分析,指出了闭环控制系数A和K对闭环控制的影响,同时研究了基于FPGA的数字闭环控制系统实现方法以及采用VHDL语言进行FPGA软件设计的优点,并给出了基于FPGA设计的光纤陀螺的实验结果。

This paper focuses on the method of signal processing of digital closed loop fiber optic gyros (FOG), and gives a detailed analysis. It points out how the closed loop control coefficients A and K , which influence the closed loop control system. At the same time it studies how to realize the digital closed loop control system based on FPGA and the design of FPGA software adopting VHDL language. Finally the experiment result of FOG based on FPGA designing is presented.
