Active Magnetic Levitation Technology

Author: Adam Krzysztof Pilat

Active magnetic levitation technology allows for non-contact transfer/movement of ferromagnetic
components. Therefore, it can be used where absolute cleanliness of the working environment,
elimination of friction or full control of dynamics is required. Areas of application include active
vibration eliminators, rotating machines, pumps, compressors, positioning tables. Their operation
requires energy, the demand for which can be minimized by hybrid solutions through the use of
permanent magnets. In active magnetic levitation systems, the key role is played by the control method
used, which we implement in the form of linear, nonlinear and intelligent control algorithms. Developed
prototypes are designed using the virtual prototyping method, in which a complete mathematical model
is solved in a numerical environment taking into account geometric properties, material properties, laws
of physics, motion dynamics and control method. Evaluation of control quality, functionality as well as
optimization of the virtual prototype makes it possible to reduce the cost of building prototypes. More,
such a functional model lower prototyping costs and makes it possible to develop new devices and study
their functionality including operational under simulated conditions, as well as to develop new, robust
and intelligent control methods.
