DAMPING GYROSCOPES UNITS OUTPUT SIGNAL GENERATION SYSTEM Russian patent published in 2018 - IPC G01C19/00 

FIELD: instrument engineering.

SUBSTANCE: invention relates to the field of navigation instrumentation, and can be used in automatic control systems, for example, of the aircraft. On each of the three measuring channels, the damping gyroscopes units output signal generation system contains the n damping gyroscopes units, each unit consists of two angular velocity sensors with the input axes same orientation. Angular velocity sensors gyro motors are connected to the power supply unit through the corresponding pulse transformers primary windings, which secondary windings are connected to the corresponding gyro motors rotation control units first and second inputs, which issue the failure signal with one of the angular velocity sensors in the damping gyro unit failure. 2n angular velocity sensors outputs are connected to the output signal generation unit signal inputs, to which control inputs the gyro motors rotation n control units outputs are connected. Output signal generation unit output signal is determined by the expression , where k = 1, 2, ..., n corresponds to the number of any normally functioning damping gyro units; U_out is the output signal generation unit output voltage; K_dci, H_i, c_i, ΔU_i are the angle sensor steepness, kinetic moment, spring stiffness, the i-th angular velocity sensor measurement error; ω_x is the measuring channel input angular velocity. From the expression for the output signal, it follows that the angular velocity measurement accuracy depends on a large number of design parameters, which have deviations from the nominal values by random law. Therefore, by averaging all the included into the DGU AVS signals and operating on one measurement channel, we obtain the total error averaging and, consequently, an increase in the measurement accuracy without reducing the operation reliability.

EFFECT: increased accuracy.
