摘要：A piezo actuator system, is presented herein. A piezo actuator systemcomprises a number of piezo actuators which may lengthen and shear. Using thelengthening and shearing, the piezo actuator system grips and moves an object inresponse to a first and a second control signal, respectively. The possible displacementof the object is limited by the maximum shear of the piezo actuators. To increase thepossible displacement, the piezo actuators may be controlled to perform a linear shearsequence or a shuffle sequence. During the linear shear sequence, the object is moved;during the shuffle sequence the object is substantially stationary, while the piezoactuators are repositioned with respect to the object, after which the object may bemoved further using the linear shear sequence. A piezo actuator system may be adapted
to perform a slow shuffle sequence, being a relatively slowly performed shufflesequence, during which the linear shear sequence may be performed simultaneously,preventing any dead time during movement.
