Inverse Compensation for Hysteresis in Magnetostrictive Transducers
This paper addresses the development of inverse compensation techniques for a class of ferromagnetic transducers including magnetostrictive actuators. If unaccommodated, the hys-teresis and nonlinear dynamics can produce severe loss of control authority and potential instabilities when the actuators are incorporated in control design. In this work, hysteresis is modeled through the domain wall ...

A Structural-magnetic Strain Model for Magnetostrictive Transducers
This paper addresses the modeling of strains generated by magnetostrictive transducers in response to applied magnetic elds. The measured strains are dependent upon both the rotation of moments within the material in response to the eld and the elastic properties of the material. The magnetic behavior is characterized through the consideration of the Jiles-Atherton mean eld theory for ferromagn...
متن کاملAn Active and Structural Strain Model for Magnetostrictive Transducers
We consider the modeling of strains generated by magnetostrictive materials in response to applied magnetic elds. The active or external component of the strain is due to the rotation of magnetic moments within the material to align with the applied eld. This is characterized through consideration of the Jiles-Atherton mean eld theory for ferromagnetic hysteresis in combination with a quadratic...
متن کاملA Free Energy Model for Hysteresis in Magnetostrictive Transducers
This paper addresses the development of a free energy model for magnetostrictive transducers operating in hysteretic and nonlinear regimes. Such models are required both for material and system characterization and for model-based control design. The model is constructed in two steps. In the first, Helmholtz and Gibbs free energy relations are constructed for homogeneous materials with constant...
