摘要
The piezo-actuated positioning stages contain two parts: Piezo Electric Actuator (PEA) and positioning mechanism. The tracking control accuracy of the piezo-actuated positioning stage is limited due to hysteretic nonlinearity of the PEA and friction behavior of the positioning mechanism. This loss in precision restricts the use of the piezo-actuated stage in ultra-high-precision optical system. This paper presents an inversion-based approach to compensate the nonlinearity of the PEA by the proposed hysteresis observer. To compensate the degrading of precision due to friction behavior of the positioning mechanism, a PI feedback controller with feed-forward controller based on the hysteresis observer is proposed to solve tracking problems with modelling uncertainties and external disturbances.
