摘要：One of the trends of mechatronics system devel-opment is reducing the size of the systems. This featurecan be achieved by employing multi-degree of freedom(multi-DOF) piezoelectric actuators [1-7]. Development ofmulti-DOF actuator is complex engineering problem. Usu-ally two design principles are used to build this type ofactuator i.e. complex design of the oscillator is used orspecific electrode pattern of piezoelectric transducer isapplied. Authors introduce another way to build a multi-DOF actuator that is to use transducer with two vectors ofpolarization and appropriate pattern of electrodes respec-tively [1, 7, 8]. Independent oscillations of contact point inthree directions can be achieved applying different controlschemes of the electrodes.
