Initial control experiments on a magnetostrictive wire clamp assembly

摘要

Abstract: This paper reports the initial control experiments performed on a small magnetostrictive wire clamp assembly. Linear, lumped parameter, dynamic models are formulated based on magnetostrictive constitutive relations. Reduced order models are utilized to understand the expected performance in terms of the system parameters (e.g., the magnetoelastic parameters). It is shown that proportional flux rate $phi feedback is fairly ineffective if used alone. Experimental results of proportional current feedback control are given. The models reported are useful for control analysis and actuator/sensor design.!6
