Electronic control circuits for the new generation of active vibroprotection devices

The features of electronic control circuits for the new design of active vibroprotection devices (AVD) have been investigated, those include the extended active frequency range and increased maximum vibration suppression coefficient. It was shown that the developed schematic and structural solutions allow using standard piezoelectric accelerometers in the control circuits of the new AVD. For these accelerometers high transmission coefficient is coupled with low resonance frequency and great parasitic signal caused by temperature changes.
