| Abstract | The paper reveals design and implementation of a magnetic actuation system (MAS) with non-invasive displacement measurement by current sensing only. Platform-independent MAS modeling methodology is utilized, describing the cross-coupled system behavior by physical representation of mechanical and electromagnetic counterparts. An extended non-linear inductor model is developed, demonstrating the challenging control task of displacement regulation. The inductor model facilitates the development of a combined current sensing methodology employing non-invasive displacement measurement. The combined sensor, based on adding a “shunt inductor” in series to the main actuator, performs both high resolution displacement and dc current measurement with fast response and minimum losses. MAS model and the combined sensor based operation have been experimentally verified on a singleaxis levitator prototype. |
