North American automotive manufacturers are preparing for a government mandate to significantly increase fuel efficiency ratings. Similar policies have already begun to be implemented in Europe. Hence, there is an immediate need to make vehicles lighter, and in turn more fuel efficient. Shape Memory Alloy (SMA) actuators have been identified to play an instrumental role in achieving these goals; however, until now applications have been restricted due their limited functionality. Smarter Alloys Inc. has overcome many of these challenges with their revolutionary Multiple Memory Material (MMM) technology. However, the MMM needs to be characterized and properly be modeled to be used as actuators in industry. This project aims at modeling of MMM, and design of a control strategy in which the MMM actuator can accurately produce force/displacement through real-time current control.

北美汽车制造商正在为政府授权大幅提高燃油效率评级做准备。类似的政策已经在欧洲开始实施。因此，迫切需要使车辆更轻，从而提高燃料效率。形状记忆合金（SMA）致动器已被确定在实现这些目标方面发挥重要作用;然而，到目前为止，由于其功能有限，应用受到限制。智能合金公司凭借其革命性的多重记忆材料（MMM）技术，然而，MMM需要被表征和适当地建模以用作工业中的致动器。本计画旨在建立磁记忆马达的模型，并设计一种控制策略，使磁记忆马达的驱动器能借由实时电流控制来精确地产生力/位移。
