METHOD FOR CONTROLLING THE PHYSICAL PARAMETERS OF THE RESONATOR OF A SOLID-STATE WAVE GYROSCOPE Russian patent published in 2022 - IPC G01C19/56 

FIELD: solid-state wave gyroscopes.

SUBSTANCE: invention relates to solid-state wave gyroscopes (SWG) having a control system for correcting their own stiffness axes. The method for controling the physical parameters of the SWG resonator is to fix the SWG sensor in the tooling for picking up and transmitting signals to the control unit. At the same time, dynamic tests are carried out, consisting of a sequence of switching modes: transient, free run-out, transient, wave rotation, and the change in the angular orientation of the standing wave is carried out without external influence by creating a controlled drift by maintaining a given value of the quadrature component of the SWG resonator oscillations. The physical parameters of the resonator are measured by recording the own dynamics of the resonator oscillations without the influence of the control system in various angular positions of the standing wave, and to carry out measurements in the free run-out mode in various angular orientations of the standing wave, the angular position of the wave is changed by maintaining the drift velocity directly proportional to the quadrature value.

EFFECT: simplification of the process of determining the physical parameters of the TVG resonator due to the exclusion of external influence on the resonator.
