Investigation of Algorithms for Identification of Wave Parameters in Solid-State Wave Gyroscopes without Adjusting Calculations to the Frequency of Signals

To improve the efficiency of production operations diagnostics, adjustment and control in manufacture integrating solid-state wave gyroscopes, algorithms for improving accuracy identification parameters from measuring signals without their additional to frequency are considered. In first algorithm processing measurement results, a virtual transition moving axes standing waves was introduced taking into account influence quadrature wave. It is characterized by lowest potential accuracy, but it convenient formation initial approximations problems clarifying optimization functions other algorithms. The second based on direct five-parameter numerical minimization error feature conjugate gradient method. avoid local extremes, recommended use as clarifier. this case, search points calculated therefore selected near extremum. This allows at shortest time intervals, which may be required when high angular velocities. third algorithm, computational conditionality improved short intervals increased level noise. fourth results processed using procedures digital demodulation under noise conditions. Comparison carried out methods simulation modeling theoretically set signals. made possible comparison identified characteristics processes: amplitudes main waves, angle its frequency. For four considered, absence presence given. diagrams errors analyzed depending length interval with fixed variable proportion sampling frequencies resonator oscillations. there standard (up 20 percent basic amplitude oscillations). obtained showed advantages disadvantages corresponding algorithms, important practical working real samples gyroscopes.
