Nonlinear 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 کاملNonlinear Optimal Control of Plate Structures Using Magnetostrictive Actuators
A nonlinear optimal control method is developed for magnetostrictive actuators used to actively attenuate plate vibration. Significant improvements in vibration control can be achieved when the magnetostrictive actuators are driven at moderate to high field levels. This results in nonlinearity and hysteresis which cannot be effectively compensated using linear control theory. This issue is addr...
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 کاملModeling 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 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...
