Abstract
A sensitive element, its geometric features, and errors affecting the performance characteristics of the product are considered in this article. The analysis was carried out, which showed that the main contribution to the self-care of the angle is made by such errors as elastic-mass defects of the quartz resonator, inaccuracy of the assembly of the structure, errors in the shooting and control system, geometric errors of the resonator. The influence of such errors as the frequency response and the quality difference on the final characteristics of the navigation device is estimated. An urgent task is to improve the control component and increase the accuracy of the entire measuring system of a solid-state wave gyroscope. The use of adaptive automatic control systems provides setting the resonant frequency of the sensitive element, capturing the natural frequency of oscillations, generating signals of the mismatch of the amplitude of oscillations, etc. To improve the efficiency of the automatic control system, to reduce the time to bring the device to the required level of quality, a mathematical model is being developed. This article discusses the model of the circuit of automatic suppression of dissimilarity for the push-pull control system of a solid-state wave gyro. An assumption has been made that it is possible to apply the results of simulation modeling for the further implementation of the circuit of suppressing different-Q-factors in the navigation block.
