How the reference voltage of electromagnetic control sensors affects the drift of wave solid-state gyroscopes

Resumo

Oscillation dynamics of a wave solid-state gyroscope with a resonator in the form of a thin elastic rotary shell mounted on a movable base is considered. A new mathematical model of the gyroscope, describing nonlinear interrelated electromagnetic and mechanical oscillations in the case that the coils of electromagnetic sensors carry voltage has been developed. Analytical estimation and numerical evaluation of the gyroscope errors have been performed.
