High precision control for nano-positioner actuated by smart materials

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The nano-positioner is composed of two piezo electric actuators (PEA) and a positioning mechanism (PM). Due to existence of hysteretic nonlinearity in the PEA and the friction in the PM, the high precision control for the positioner is a challenging task. This paper discusses the high precision adaptive control for the positioner, where the hysteresis is described by Prandtl-Ishlinskii model. The proposed control law ensures the global stability of the controlled stage, and the position error can be controlled to approach to zero asymptotically. Experimental results show the effectiveness of the proposed method.
