| Talk Title: | Controlling a Magnetic Levitation Positioning System |
| Slides: | 9-1.pdf |
| Abstract: | High-precision positioning systems are ubiquitous in industry. Currently, most high-precision positioning systems require multiple degrees-of-freedom (DOF) and multi-stage mechanical and piezo actuators to achieve both large scale (centimeter) and small scale (nanometer) positioning. Where mechanical actuators are used, there is the risk of introducing impurities from mechanical wear, and costly maintenance is always possible. Contactless positioning using magnetic levitation is developing into an attractive alternative as a single-stage system capable of large and small scale motion with high precision. We investigate a 5-DOF positioning system using iron-cored permanent magnet linear synchronous motors. Tracking controllers and path following controllers show the diversity of control strategies that can be implemented to achieve different goals. |

| Author Bio: | I am a M.A.Sc. student supervised by Professor Maggiore in the Systems Control Group at the University of Toronto. I received my B.A.Sc. in Computer Engineering from the University of Waterloo in 2005. I will be graduating from U of T this summer and beginning work at Quanser Consulting Inc. My research involves the control of a high-precision magnetic levitation positioning system, which is an ongoing research project in the SCG. |
