Development of a Magnetic Shape Memory Based Mechatronic System

这项转让项目提案的主要目标是实现基于磁性形状记忆(MSM)合金的机电一体化定位系统。该系统的结构是根据申请者LPA和合作伙伴ETO Magic GmbH在MSM执行器领域的经验选择的。双方都认为，与现有技术相比，推-推配置可以带来几个优势，最重要的是可以有利地利用材料的内摩擦力(孪生应力)在不供电的情况下保持位置。应从设计和控制的角度对MSM推进式执行器进行分析。将采取几个步骤将基本思想带到一个完全工作的机电系统中，该系统满足定位工具的规格。这些步骤包括适当控制器的稳定性分析(经典的比例积分导数控制器、自适应控制器、鲁棒控制器、基于模型的控制器等…)研究活性材料的固有传感能力，以及开发确保感兴趣的工作带宽的专用电流源。本文提出的工作目标是MSM定位系统的工作演示。

The main goal of this transfer project proposal is the realization of a mechatronic positioning system based on magnetic shape memory (MSM) alloys. The structure of the system has been chosen based on the experience of the applicant LPA and the collaborating partner ETO MAGNETIC GmbH in the field of MSM actuators. Both partners believe that the push-push configuration can lead to several advantages with respect to the state of the art, foremost the possibility to use the internal friction forces of the material (twinning stress) advantageously to hold a position without supplying power. The MSM push-push actuator shall be analyzed from both a design and control point of view. Several steps will be taken to bring the basic idea to a fully working mechatronic system which satisfies the specifications of a positioning tool. These steps include the stability analysis of suitable controllers (classical proportional-integral-derivative, adaptive, robust, model-based, etc…), the investigation of the inherent sensing capability of the active material and the development of an application-specific current source which ensures the working bandwidth of interest. The target of the work proposed here is a working demonstrator of an MSM positioning system.
