Comprehensive review and analysis of the electromagnetic levitation systems (modeling, controllers, nonlinearity sources)

Abstract

Magnetic Levitation Systems (MLS) is a higher advanced technology without any mechanical contact that results in zero friction losses. Such technology offers a low cost of maintenance, precise operation, very clean working, not noisy and quiet, remotely controlled, and small size. These features make it utilize with various important applications in different fields and different industries sectors, it can be applied in the vibration absorber, Biomedical applications or devices, very fast transport technology, etc. It is very well known that the (MLS) are non-linear and unstable open-loop, hence, numerous approaches are considered for non-linear control techniques to present a variety of results. The aim of our analysis in this article is to introduce the system's nature and behavior and to learn about the system's components as well as to cover most of the applied controlling approaches that were suggested by researchers to acquire the best performance.
