DEVICE FOR MEASURING ACCELERATIONS Russian patent published in 2023 - IPC G01P15/13 G01C9/02 

FIELD: navigation and stabilization systems.

SUBSTANCE: design includes an analog negative feedback from the output of the band-pass filter to one of the inputs of the torque sensor through a differentiating link, the other input of the torque sensor is connected to the output of an asynchronous RS-trigger through a threshold element with an ambiguity zone, and the output the threshold element with the ambiguity zone is connected to the input of the torque sensor through a smoothing filter of the third order, and the output of the synchronous JK flip-flop is connected to two waiting synchronous generators through the integrator. In addition, the bandpass filter is connected to the first emitter repeater through a saturating integrating amplifier, in the return circuit of which a filter with a transfer function W(s)=(T₁·s)/(T₁·s+1) is introduced, and the output of the second reverse binary counter is a discrete output of the device for measuring accelerations. Introduction of analog and discrete negative feedback into the claimed device makes it possible to create a self-oscillating system with an extended bandwidth and provide astatic deviation. Introduction of a differentiating link into the analog negative feedback ensures stability and stabilization of the parameters of the device for measuring accelerations.

EFFECT: improvement of measurement accuracy and expansion of bandwidth.
