Design and Modelling of a Sensor-Integrated Actuator Using Combined Effects of Magnetostriction and Piezoelectricity

Abstract:
This paper presents a magnetostrictive actuator integrated with a piezoelectric sensor. The output force can be detected during actuation. A nonlinear model to depict the combined effects of magnetostriction and piezoelectricity is proposed. The model for magnetostriction is based on the Jiles-Atherton model with dynamic extensions of eddy-current losses and magneto-mechanical effects, so it applies for the working conditions of high frequency and time-varying stress. A piezoelectric constitutive model is connected to the new Jiles- Atherton model with both the changing strain and the changing interaction forces. Using the combined model, the output displacement of the sensor-integrated actuator can be accurately predicted. Simulations and
experiments have been conducted and compared for verification.
