Papko A.A. On realizability postulates of specific dynamic behavior and vibrostability of precision low-frequency accelerometers

The problems of providing the desired dynamic behavior and the vibrostability of balancing transform accelerometers are discussed. The paper proves that accelerometer’s dynamic behavior depends not so much on how the correcting link is connected as on whether the link belongs to direct or inverse transformation circuits. The results of synthesizing the correcting devices that enable dynamic behavior adjustment for the accelerometers with deep negative feedback are included. It is shown that the ways of dynamic behavior optimization based on the estimates of the output signal compliance with specific requirements do not ensure positive results in real-life devices where components operation is limited by the finite values of displacements, supply voltages, power, etc.
