Magneto-electro-mechanical modeling of magnetic actuation systems

This study presents a new modeling methodology for magnetic actuation systems (MAS) that can be realized on a single simulation platform and is applicable in the majority of present-day simulation tools. The main benefit of the modeling approach is that it significantly reduces the complexity and burden in the design and control of multidisciplinary systems. The method describes the behavior of the system by the physical representation of the individual counterparts. The behavior of an actuator is described by cross-coupled models of the mechanical and the electromagnetic interaction. An extended, non-linear inductor model has been developed, demonstrating the challenging control task of displacement regulation. The MAS model and the individual models have been verified experimentally on a single-axis levitator prototype.
