Hysteresis compensation in GMA actuators using Duhem model

Abstract

Giant magnetostrictive material (GMM) is gathering more interests due to its superior electromechanical properties. Though the strain of GMM is almost larger than PZT, it still needs to be amplified to match practical demands. A press-bend amplification based giant magnetostrictive actuator (GMA) is designed and the electromechanical system model is… (More)
