| Abstract: | It is important to foreknow the hysteresis characteristic when using piezoceramic actuator for precision micropositioning.An computer based system was designed to get the hysteresis curve of piezoceramic stack automatically.PC486 and a data acquisition card PCL-818L are the elementary part.High-voltage amplifier was necessary to supply voltage above 100V.A common proximitor followed by amplifier was used to measure the displacement instead of expensive capacitive sensor.Hystersis curves of stack to different range of triangle-wave/sine-wave voltage were acquired. |
