METHOD OF FEEDBACK SIGNAL RECEPTION BY SPEED OF INDICATOR GYROSCOPIC PLATFORM AND INDICATOR GYROSCOPIC PLATFORM Russian patent published in 2020 - IPC G01C19/22 

FIELD: instrument engineering.

SUBSTANCE: inventions relate to accurate instrument-making, namely to gyroscopic equipment, and can be used in indicator gyrostabilizers. Method of obtaining a feedback signal on the speed of the indicator gyroscopic platform is characterized by the fact that a signal from a tachometric bridge which is proportional to the angular velocity of the platform is transmitted in a certain phase to a differential amplifier and is supplied to the adder of the power amplifier with the required amplification factor. Indicator gyroscopic platform, which includes a gyroscope and two channels, containing differential angle sensors connected through stabilization amplifiers with appropriate platform stabilization motors, a sensor of torque in each channel, platform control inputs, platform angle sensors. At that, at the output of the stabilization amplifier, a tachymetric bridge is additionally introduced on each channel, one arm of which is arranged on two resistors, and the other arm is arranged from the winding of the stabilization motor and an additional resistor, signal from which in a certain phase through a differential amplifier after amplitude conversion is supplied to adder of input of power amplifier of platform stabilization amplifier.

EFFECT: technical result of inventions is high stability of system by receiving feedback signal on speed stabilization channels of gyrostabilizer.
