— This paper is concerned with multivariable coupled hysteretic systems. The traditional Bouc-Wen monovariable hys-teresis model devoted to one degrees of freedom (DoF) actuated systems is extended to model the hysteresis in systems with multiple DoF which typify strong cross-couplings. The proposed approach is able to model and to compensate for known(More)
In the literature, the generalized Bouc-Wen model can track precisely asymmet-ric hysteresis nonlinearity. In this paper, we propose to extend this generalized model to multivariable hysteresis model that can track the nonlinearities in multi-degrees of freedom (multi-DoF) hysteretic actuated systems. In particular, these systems are typified by strong(More)
— The present paper deals with the motion control of a piezoelectric cantilevered actuator for different frequencies regimes. The motion behavior of the piezoelectric cantilever is affected by two main parasitic effects, the hysteresis and creep effects, which are considered as a generalized disturbance. Additionally, cantilevers's position is the only(More)
— This paper deals with the modeling, identification and feedforward control of hysteresis found in multi-degrees of freedom (DOF) piezoelectric actuators. One main characteristic of the considered hysteresis behavior is the strong couplings. To express such multivariable hysteresis, we propose to extend the previous Bouc-Wen hysteresis monovariable model(More)
