Because of the advancing modern control systems theory and computing, the regulation of complex nonlinear systems, without large auxiliary electronics or sensor systems is becoming more and more attainable.
Trough the design of a magnetic levitation device, one can face almost all the trouble that could surface during the shaping of a nonlinear feedback system: the difficulty and swiftness of the feedback, the signal processing and the effect of external disturbance.
The aim of the thesis is not only to create a magnetic levitation device, but to look at the system from a different point of view, discover new possibilities and unravel various causes and effects as well.
The high-frequency position-detection method, which is one of the main issues of the thesis, is a process that possesses several benefits and drawbacks, and might be a powerful asset in certain applications. It can be declared, that the position detection based on impedance-measurement is working and is sufficiently accurate, as the measurements prove. However, it is yet immature, because this thesis is only the first step in a long road that leads to the utilization of this technology.
