Active Magnetic Bearing Interdisciplinary Design Modelling and Control Tool

This elaboration presents a modern approach in the field of active magnetic bearing design based on computations supported by partial differential equations (PDEs) and ordinary differential equations (ODEs). The magnetic field problems are solved using the finite element method (FEM), while the levitating rotor motion is calculated using ODEs. The novel Active Magnetic Bearing Interdisciplinary Design Modelling and Control (AMBIDMC) study tool was developed customising COMSOL Multiphysics and MATLAB software. This paper summarises the author’s recent work in the field of integrated active magnetic levitation (AML) systems design and modelling including control and motion dynamics. A discussion of the features and limitations of the field of control systems is provided in this paper, showing how the developed model can be useful for controller studies. The discussion is illustrated by simulation data collected from working virtual prototypes.
