Hysteresis cancellation using self-sensing actuation in a multistack actuator

抄録

For high voltages, large hystereses are usually observed in multi-stack actuators. To cancel it, either hysteresis modeling or closed loop system can be used. To overcome the limitations of both techniques, we present here an application of the correlation of the strain and polarization to build a self-sensing hysteresis cancellation. The advantage of this technique is to remain efficient for various voltage profiles and don't require additional sensor.
