Fast Evaluation of Demagnetizing Field in Three Dimensional Micromagnetics using Multipole Approximation
Computational micromagnetics in three dimensions is of increasing interest with the development of magnetostrictivesensors and actuators. <p>In solving the Landau-Lifshitz-Gilbert (LLG) equation, the governing equation of ...
Control of Smart Actuators: A Viscosity Solutions Approach
Hysteresis in smart materials hinders their wider applicability in actuators. In this report we investigate control of smart actuators through the example of controlling a commercially available magnetostrictive actuator. ...
Control of Hysteresis: Theory and Experimental Results
Hysteresis in smart materials hinders the wider applicability ofsuch materials in actuators. In this paper, a systematic approachfor coping with hysteresis is presented. The method is illustratedthrough the example of ...
Cayley Transforms in Micromagnetics
Methods of numerical integration of ordinary differential equations exploiting the Cayley transform arise in a variety of contexts, ranging from the classical mid-point rule to symplectic and (almost) Poisson integrators, ...
