Aerospace Instrument-Making Annotation << Back On the lower stability dynamically tuned gyroscope mode biaxial angular velocity sensor as compared to uniaxial Chernikov S.А. Stability of a two-axis angular rate sensor, built on the basis of dynamically tuned gyro-scope. The characteristic polynomial dual girosistemy with identical channels decom-posed into factors, each of which is equal to zero. The resulting two equations with complex coefficients are equivalent in terms of sustainability, the characteristic equation of biaxial system. Thus, the question of the stability of two-component angular velocity sensor is to analyze the characteristic equations of equivalent systems. Based on the frequency method, simple analytical expressions for the stability boundary of the two-dimensional system, and the reduction ratio of the two-dimensional degree of stability compared to the one-dimensional, depending on the bandwidth of separate channels. It is shown that the destabilizing effect of the relationship of uniaxial channels girosistemy may be larger than those of their stability, ensuring the required quality of measurement of the angular. Key words: dynamically tuned gyro, speed sensor, sustainability. Contacts: E-mail: sa chernikov@mail.ru Pp. 51-56.
