Design of Digitized Force Feedback Loop in Dynamically Tuned Gyro based on DSP and FPGA

This article first presents the Dynamically Tuned Gyro(DTG) force feedback loop transfer model.Aiming at the limitations such as noise,drift influence and low precision in the Analog Force Feedback Loop,the article proposes one digitized plan,and addresses its design and the solution.Digital Signal Processor(DSP) and Field Programmable Gate Array(FPGA) are applied in the design,using the digital loop circuit could effectively reduces the noise and drift influence of inherent factor in the analog loop circuit,and so it has achieved a higher precision.The experiment has proved this plan has the good usability and efficiency.
