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.

该转让项目提案的主要目标是实现基于磁性形状记忆（MSM）合金的机电定位系统。该系统的结构是根据申请人LPA和合作伙伴ETO MAGNETIC GmbH在MSM执行器领域的经验选择的。两个合作伙伴都认为，相对于现有技术，推-推配置可以产生几个优点，最重要的是可以有利地使用材料的内摩擦力（孪生应力）来保持位置而不供应功率。应从设计和控制两个角度分析MSM推-推致动器。将采取几个步骤，使基本思想，以充分工作的机电系统，满足规格的定位工具。这些步骤包括合适的控制器（经典的比例-积分-微分，自适应，鲁棒，基于模型等）的稳定性分析，活性材料的固有传感能力的研究和特定应用的电流源，确保工作带宽的发展。这里提出的工作的目标是一个MSM定位系统的工作演示。
