In order to obtain precision tracking control, Prandtl-Ishlinskii (PI) model is used to model the hysteresis nonlinearity. Then, the inverse PI model is used to reduce the hysteresis nonlinearity and a sliding-mode controller is used to compensate the remaining nonlinear uncertainty and disturbances. The piezoelectric-actuated system is modeled as a linear model coupled with a hysteresis. The linear model is identified then it is used to design the sliding-mode controller. Finally, experimental results are presented to verify the usefulness of this method. ?2007 IEEE.ElasticityHysteresisIndustrial engineeringMathematical modelsNavigationPiezoelectricitySliding mode controlControl and automationHysteresis non-linearityLinear modelingNonlinear uncertaintiesPrecision tracking controlControl systemsconference paper10.1109/MED.2007.44339072-s2.0-50249127197
