报告内容简介：
The nano-positioner is composed of a piezo electric actuator
(PEA) and a positioning mechanism (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.
