Research on Digital Closed Loop FOG Based on FPGA

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.
