COMPENSATION ACCELEROMETER Russian patent published in 2018 - IPC G01P15/13 

FIELD: instrument engineering.

SUBSTANCE: invention, the compensating accelerometer, is intended for use as an element in the stabilization and navigation systems. Invention can be used in the mechanical values compensation type measurement instruments. Essence of the claimed solution is in the fact that the compensation accelerometer contains the sensitive element, position sensor, which output is connected to one of the “or” excluding circuit inputs through the amplifier and the first logic element, magnetoelectric power converter, included into the negative feedback, the reference voltage generator, which outputs are connected both to the position sensor and to one of the “or” excluding circuit inputs through the second logic element, level converter connected to the reversible binary counter input through a pair of waiting synchronous generators, a synchronization circuit, an integrator, introduced are relay element with the ambiguity zone from the “or” excluding circuit output to the level converter input and an integrator from one of the amplifier inputs to its output, in addition, one of the relay element with the ambiguity zone outputs is connected to the magnetoelectric power converter input, the relay element with the ambiguity zone and the waiting synchronous generators additional inputs are connected to the synchronization circuit output, and the negative feedback is implemented from the amplifier output to the torque sensor input through the in series connected via information inputs first logic element, the “or” excluding circuit, the relay element with the ambiguity zone, and the reversible binary counter output is the device digital output.

EFFECT: relay element with an ambiguity zone introduction into the compensation accelerometer into the negative feedback and the integrator into the amplifier direct coupling allowed to implement the self-oscillations mode, to increase the gain around the open loop without loss of stability; in addition, the integrator introduction from the position sensor output to the amplifier output made it possible to implement the second-order astaticism, expand the passband and improve the measurement accuracy.
