Decreasing stiffness at the cost of emerging hysteresis

Minimising power dissipation is critical for applications in cryogenic environments.


Experimental results show that the guiding stiffness, and with that the associated motor-current-induced dissipation, of a voice-coil-actuated positioning stage can be significantly decreased using a stiffness-compensation mechanism, as demonstrated by JPE in this Mikroniek article. However, as expected, the contribution of hysteresis from the compensation mechanism becomes noticeable in the force-displacement graph. (Image courtesy of JPE).
