Numerical magnetic bearing design and simulation by Finite Element Method
This project deals with the design and numerical simulation of a radial active magnetic bearing (AMB). This bearing is a Y-shaped three-pole magnetic bearing fed by two amplifiers.
The geometry design is based on the analytical computation and numerical optimization. The numerical optimization is integrated into a nonlinear finite element analysis (FEM). The nonlinearity has been handled by the Newton-Raphson method. The numerical optimization means the brute-force search and the Nelder-Mead simplex search algorithm.
The results of the two-dimensional FEM simulation have been compared with the three-dimensional simulation of the given bearing geometries. This comparison is necessary because of the importance of the end-region field effect in the magnetic bearing simulation .
The main goal of this project is to build up the magnetic bearing system and to design the nonlinear digital controller for a Y-shaped three-pole AMB system to the properly operation.
