Compensative control chart of angular velocity sensor on basis of wave solid-state gyroscope

Gankevych Z., Kucher S., Bondar P.

Vibrations in Physical Systems

2010

Vol. 24

111--116

This work is devoted to results of research wave solidstate gyroscope (WSG) with a metallic cylinder resonator and piezoelectric systems of excitation and pickup information, which works in the mode of compensation angular velocity sensor. This type of device becomes more and more attractive thanks to its low cost, considerable vibrostability, shockproof and enough high precision characteristics. In the work there are results of design the power balancing channel, which provides functioning of gyroscope in the compensative mode in the environment of MatLAB-Simulink. Numerical parameters, namely basic mode frequencies of vibration, which are used in model, were got by means of finite element analysis of real resonator model in the environment of ANSYS. It is shown that application of integral-position control law gives the desired dynamic characteristics both to the action of permanent angular speed and to the change of it by harmonic law.
