Simulation Model of Magnetic Levitation Systems

摘要

For active magnetic bearings, a mathematical description of the phenomena that occurs in them is very complex and does not allow one to represent their operation without introducing many simplified assumptions. Some solutions concerning the numerical simulation of magnetic bearing dynamics are to be found in literature. These are most often simulations based on the generally accepted simplified theoretical assumptions, which do not employ real "actuator - controlled object" characteristics. An idea of building a model that represents real properties of individual system elements was developed. The operation of the proposal model is convergent with the operation of real bearing system, what has been verified experimentally. This model is characterized by a possibility of implementation of individual properties of actual operating and measurement systems of the bearing. A real structure of the bearing is non-linear, and thus the model representing actual characteristics of its component elements is non-linear as well. In this paper an idea of the simulation model of magnetic levitation systems and its diagnostic capabilities is presented.
