Characterization of a Magnetically Levitated Testbed for Electrospray Propulsion Systems
Small satellites are changing the space scene dramatically. By drastically reducing costs while still having impressive technological capabilities, their popularity among the space community is increasing at a very fast rate. Propulsion systems for these class of spacecraft are very limited. One promising technology is the ion Electrospray Propulsion System (iEPS) developed at the Space Propuls...
متن کاملExperiments on a magnetically levitated planar actuator
Magnetically levitated planar actuators are developed as alternatives to xy-drives constructed of stacked linear motors. Although the translator of these ironless planar actuators can move over relatively large distances in the xy-plane only, it has to be controlled in six degrees-of-freedom (DOF) because of the active magnetic bearing. The advantage of magnetically levitated planar actuators i...
متن کاملA High-Precision, Magnetically Levitated Positioning Stage
High accuracy positioning stages with multiple degrees-of-freedom, or microsteppers, are ubiquitous in industrial manufacturing. These devices are used in probing and inspection systems, in the assembly of disk drive heads, and in semiconductor manufacturing. In semiconductor manufacturing, microsteppers are employed to accurately move silicon wafers in the photolithography process. To guarante...
متن کاملDynamic Performance of Magnetically Levitated Rotors
Magnetic bearings are selected as the physical systems because of the recent tremendous research activity in their use in high performance machines. The input-output characteristic makes such a system inherently nonlinear and unstable, so it is necessary to implement a desired control to it. However, if the system dynamic behavior and the limitations from the control system hardware as a whole ...
متن کاملFeedforward Control of Magnetically Levitated Planar Actuators
The present report summarizes the work conducted during the internship on Feedforward Control of the Magnetic Levitation Setup. Different feedforward strategies, specifically tailored for this setup, are developed and reviewed. These feedforward methods explicitly take the intrinsic position-dependent behavior of the magnetic levitation setup into account. Additionally, closed-loop stability of...
