Development of High Performance Controllers for Active Magnetic Bearing Systems

ECS-9619785 Dawson 主动磁轴承（AMB）是一种非接触式的支撑旋转部件（如电机或泵轴）的装置。 也就是说，AMB系统可以用作标准机械接触支撑件（诸如滚子或滚珠轴承）的替代物。 AMB提供了优于传统机械轴承的几个重要优点，这可以导致各种装置（例如，可能的旋转机械系统包括电动机、发电机、汽油或柴油发动机、喷气发动机和涡轮机、风扇、鼓风机等）。 具体而言，AMB：I）不受摩擦损失的影响，ii）可用于补偿转子不平衡，iii）可在高温和低温环境下运行，以及iv）消除与润滑剂和摩擦磨损相关的污染。 该项目将是数学建模和控制算法以及相关的软件和硬件模块，用于大间隙电磁轴承的高精度控制，并用于演示其相应的应用。 具体来说，拟议中的研究将把非线性理论的最新进展带到一个新兴的技术领域，这可能为美国制造业创造一个潜在的巨大出口市场。

ECS-9619785 Dawson The active magnetic bearing (AMB) is a non-contact means of supporting a rotating member such as a motor or pump shaft. That is, an AMB system can be used as a substitute for standard mechanical contact supports, such as rollers or ball bearings. The AMB offers several important advantages over conventional mechanical bearings which can lead to improvements in a large variety of devices (e.g., possible rotating machine systems include electric motors, electric generators, gasoline or diesel engines, jet engines and turbines, fan, blowers, etc.). Specifically, AMBs: I) are not subject to frictional losses, ii) can be used to compensate for rotor unbalanced, iii) can operate in both high and low temperature environments, and iv) eliminate contamination associated with lubricants and friction wear. The project will be mathematical modeling and control algorithms and the associated software and hardware modules for high precision control of large gap AMBs and for the demonstration of their corresponding applications. Specifically, the proposed research will bring recent advances in nonlinear theory to an emerging technical area which could spawn a potentially large export market for U.S. manufactures.
