Abstract:
A major deficiency in piezoelectric actuator performance is caused by hysteresis and creep effects. Switched capacitor charge pump control was previously proved to be an effective way to reduce hysteresis. In this work, creep character of a piezoelectric stack under charge pump control is investigated and modeled. Experiments show that the creep can be reduced by about 77% compared with the one under voltage control. The creep factor denoting the degree of creep shows hysteresis loops similar to displacement outputs under voltage control.
