An observer-based adaptive control design for the maglev system:
TLDR
The proposed control design provides better performance than most of the robust and adaptive controllers that have been frequently used to control maglev system and performs the best tracking performance with the least control effort.Abstract:
In this study, a nonlinear adaptive controller that can be used to control a magnetic levitation (maglev) is designed. The designed controller is equipped with a nonlinear velocity observer to prov...read more

Sliding mode and classical controllers in magnetic levitation systems
TL;DR: In this paper, an experimental comparison between a sliding-mode controller and a classical controller for stabilizing and commanding a magnetic levitation system is made, where the sliding mode method can be applied to a nonlinear system in the global sense, and the issues of performance and robustness to modeling uncertainties and disturbances can be directly incorporated in the design as tradeoff parameters.
