Analysis of Error Mechanisms of Vibrating Gyroscopes Operating in a
Slowly Changing Environment 2024-01-5044
This study presents the constructed electromechanical model and the analysis of
the obtained nonlinear systems. An algorithm for compensating the nonlinear
drift of a gyroscope in a microelectromechanical system is proposed. Tests were
carried out on a precision rotating base, with the angular velocity changing as
per the program. Bench testing the gyroscope confirmed the results, which were
also supported by the parameter calibration. The analytical method was further
validated through experimental results, and a correction algorithm for the
mathematical model was developed based on the test results. After calibration
and adjusting the gyroscope’s systematic flaws, the disparity in calculating the
precession angle was within 1/100th of an angular second over an interval of
approximately 1000 s. Currently, research is underway on the new nonlinear
dynamic characteristics of electrostatically controlled microstructures. The
results of the integrated navigation system of small satellites, which
successfully passed bench tests, are presented.
