This research project deals with the development of an integrated methodology for modeling, design and control of electromagnetic systems. An approach to developing this integrated methodology consist of two basic components: Development of a modeling and design strategy for the electromagnet actuation scheme using Permanent-ElectroMagnet (PEM) combinations that support the large travel and the high stiffness performance requirements, and the formulation of a discrete time, robust nonlinear control architecture that guarantees ultra precision tracking performance under external disturbances and plant variations. This tight coupling between the design of the electromagnetic actuation scheme and that of the control architecture ensures that the entire system responds at the stringent performance levels demanded of it. Results from this project provide a clear methodology for designing electromagnetic actuation schemes given a set of performance requirements; improve the understanding of nonlinear, discrete time control in the context of high performance electromechanical systems; and enable technology that is essential for the development of magnetic suspension actuators. By adding PEM combination, the research project enhances the capabilities of the large travel Magnetic Suspension Actuator currently under development at the Coordinate Metrology and Measurement Laboratory at Ohio State University. It leads to a system that addresses the high performance actuation requirements of the precision engineering industry for a range of applications such as photolithography, semiconductor wafer inspection, free-form precision machining and non-circular turning.

本研究项目涉及电磁系统建模，设计和控制的综合方法的发展。制定这一综合方法的办法包括两个基本组成部分：为使用永磁体-电磁体（PEM）组合的电磁体致动方案开发建模和设计策略，所述组合支持大行程和高刚度性能要求，并且制定离散时间，鲁棒的非线性控制架构，保证在外部干扰和设备变化下的超精度跟踪性能。电磁致动方案的设计与控制结构的设计之间的这种紧密耦合确保了整个系统响应于所要求的严格的性能水平。提高对高性能机电系统背景下非线性、离散时间控制的理解;并实现对磁悬浮执行器开发至关重要的技术。通过添加PEM组合，该研究项目提高了俄亥俄州州立大学坐标计量和测量实验室目前正在开发的大行程磁悬浮致动器的能力。该系统可满足精密工程行业的高性能驱动要求，适用于光刻、半导体晶圆检测、自由曲面精密加工和非圆车削等一系列应用。
