Modeling Techniques for Magnetostrictive Actuators
Techniques for modeling hysteresis and material nonlinearities in magnetostrictive materials are presented. Hys-teresis in these materials is due to both the driving magnetic eld and stress relations within the material and is signiicant throughout most of the drive range of the material. Two characterizations are presented here. The rst model is posed in terms of Preisach operators and is pure...
متن کاملA Nonlinear Physics-Based Optimal Control Method for Magnetostrictive Actuators
This paper addresses the development of a nonlinear optimal control methodology for magnetostrictive actuators. At moderate to high drive levels, the output from these actuators is highly nonlinear and contains significant magnetic and magnetomechanical hysteresis. These dynamics must be accommodated by models and control laws to utilize the full capabilities of the actuators. A characterizatio...
متن کاملNonlinear Optimal Control Techniques for Vibration Attenuation Using Magnetostrictive Actuators
This paper addresses the development of a nonlinear control design for attenuating structural vibrations using magnetostrictive transducers operating in nonlinear and highly hysteretic operating regimes. We consider as a prototype a thin plate subjected to exogenous pressure waves and controlled via Terfenol-D transducers at the plate edges; however the methodology is sufficiently general to en...
متن کاملMagnetostrictive Actuators Compared to Piezoelectric Actuators
Magnetostriction occurs in the most ferromagnetic materials and leads to many effects [1,2]. The most useful one to refer to is the Joule effect. It is responsible for the expansion (positive magnetostriction) or the contraction (negative) of a rod subjected to a longitudinal static magnetic field. In a given material, this magnetostrain is quadratic and occurs always in the same direction what...
متن کاملA Nonlinear Model-Based Control Method for Magnetostrictive Actuators
A nonlinear model-based control method for magne-tostrictive actuators is presented in this paper. Such ac-tuators utilize the realignment of magnetic moments in response to applied magnetic elds to generate strains in the material. Strains and forces generated in this manner are signiicantly larger than those produced by many other smart materials but also exhibit signiicant nonlinearities and...
