Abstract
Magnetic levitation has the strong potential to be a precision force/position-controllable actuator with inherent force-sensing capability in itself. We call such a system magnetic servo levitation to distinguish it from conventional magnetic suspension-only levitation. Magnetic levitation inherently has strong instability and needs high-speed closed-loop control. There were few applications of magnetic servo levitation because high-speed digital controllers were not available. The authors developed a digital controller using a digital signal processor, and experimentally verified that magnetic servo levitation is promising and realizable by the state-of-the-art device technology.
M. Tsuda, a Ph.D. candidate at the Institute of Industrial Science, University of Tokyo, is presently a visiting researcher at the Center for Robotic Systems in Microelectronics, University of California, Santa Barbara, for collaborative research of the two institutions.
