Abstract

The feasibility of implementing embedded magnetostrictive mini actuators (MMA) for smart structure applications, such as vibration suppression of beams, is investigated in this paper. Based on the Euler-Bernoulli's beam theory and previously reported magnetothermoelastic theory of MMA, an integrated mathematical model of the beam embedded with MMA is formulated. In addition, different forms of control schemes for MMA are investigated. Simulation results, based on the open-loop control, shows that it is possible to attenuate the vibration by embedding MMA in the beam. Further work on the investigation of the merits of nonlinear closed-loop control is in progress.
