The invention belongs to the field of precision driving, and particularly relates to a piezoelectric driving rotary motion device and a control method thereof. The inchworm type piezoelectric drivingdevice solves the technical problems that an inchworm type piezoelectric driving device is complex in structure and difficult to control. The device comprises a driving unit, a clamping unit, a rotor,a screw and a base; and the driving unit and the clamping unit are installed on the base through screws. According to the device, through sequential control over voltage signals, the driving unit andthe clamping unit alternately and cooperatively work, large-stroke high-precision rotating motion can be achieved, and the device can be applied to the fields of precision and ultra-precision machining, micro electro mechanical systems, micro-operation robots, biotechnologies, aerospace and the like. 本发明属于精密驱动领域，具体涉及一种压电驱动的旋转运动装置及其控制方法。本发明解决了尺蠖型压电驱动装置结构复杂、控制困难的技术问题。该装置包括驱动单元、钳位单元、转子、螺钉和底座；驱动单元和钳位单元通过螺钉安装在底座上；该装置通过对电压信号的时序控
