    The nano-positioner is composed of a piezo electric actuator(PEA) and a positioning echanism (PM). Due to the existence of hysteretic nonlinearity in the PEA and the friction in the PM, the high precision control of the piezo-actuated positioner is a challenging task. This research discusses the high precision control for the piezo-actuated stage by using the adaptive method.  The proposed control law ensures the global stability of the controlled positioner, and the position error can be controlled to approach to
zero asymptotically. Experimental results show the effectiveness of the proposed method.
