INDICATOR GYROSTABILIZER Russian patent published in 2023 - IPC G01C19/04 G01C19/56 

FIELD: precision instrumentation.

SUBSTANCE: used in indicator gyrostabilizers and tracking systems. The essence of the proposed device is as follows. The indicator gyrostabilizer, which contains a stabilized platform cinematically connected to the unloading device, a gyroscope, a phase detector, and negative feedback, has analog and discrete negative feedbacks, and the analog negative feedback is implemented from the output of the amplifier with saturation, to one of its inputs the first integrator and the delay element series-connected by information inputs. Discrete negative feedback is implemented from the output of the comparator to the input of the unloading device through a level converter, two standby synchronous generators, a reversible binary counter, a comparison circuit, a trigger, an electronic key, the input of which is connected to the output of the current generator, a summing binary counter, series-connected by information inputs, the output of which is connected to one of the inputs of the comparison circuit, and the input to the output of the auxiliary frequency generator, the reference voltage generator, the output of which is connected to the input of the phase detector, the additional inputs of the comparator, two standby synchronous generators, the reversible binary counter are connected to the auxiliary frequency generator, and the output of the phase detector is connected to the input of the comparator through a broadband differentiating filter and a second integrator connected in series. The input of the amplifier with saturation is connected to the output of the gyroscope, and one of the outputs is connected to the input of the phase detector.

EFFECT: improving the stabilization accuracy and expanding the bandwidth.
