    Abstract
  • A mathematical model for digital closed-loop FOG(fiber-optics gyroscropes) was established to get the difference equation of the model. Also, the differential equation and transfer function corresponding to the model were deduced. Frequency characteristics calculation of the digital closed-loop FOG was conducted based on error analysis between the transfer function and the model. A method found for testing frequency characteristics of the digital closed-loop FOG on common speed platform was established. The validity and veracity of the methods were verified by comparing the testing and calculation data.
