Modeling and control for nonlinear systems with hysteresis

This paper introduces the research achievement of nonlinear systems with hysteresis,which is a non-smooth and multi-valued-mapping nonlinearity.It focuses on the latest approaches of modeling and controller design for systems with hystereis nonlinearity.The comparison and analysis of the two most popular models used in controller design,i.e.Preisach model and linear models,are presented in order to show their advantages and disadvantages.Then,the inverse_model based compensation schemes including the dynamical control and the static control are illustrated to compare their features,difference,and the conditions for applications.Moreover,some other controllers are also briefly described.At last,a discussion on the research in the future is given.
