Abstract:

The technique of selective torque frequency control as applied to an acceleration switching servo was shown to provide damping in the frequency region of mechanical resonance and yet retain high servo torque stiffness in the low frequency region. This may be accomplished in many systems by simply designing a conventional acceleration switching servo and appropriately selecting the gain distribution and multivibrator repetition rate to give desired amount of synthetic damping. Additional damping may be provided by the addition of a load damping orifice without sacrificing low frequency stiffness. Author
