Design and control of linear actuators made by magnetically controlled shape memory alloy

Abstract

This paper introduces the basic structure of a magnetically controlled shape memory alloy (MSMA) actuators based on the actuation principle of the NiMnGa alloys under external magnetic field. A new differential control strategy of MSMA actuator was proposed and the differential linear MSMA actuator has been built and tested. The new MSMA actuator has the… (More)
