Abstract

A magnetic bearing is a bearing which supports a load using magnetic levitation. Magnetic bearings support moving machinery without physical contact. It can be divided into two categories which are passive and active magnetic bearing. For active magnetic bearing, the force on the rotor can be controlled by changing the current flow through the magnet coils. The problem exist is that it can only exert an attractive force that cause the system inherently unstable and requiring the use of controller. The objectives of the project are to design fuzzy logic controller which is able to stabilize the position of the rotor of magnetic bearing system and to analyze the performance of the controlled system using Matlab/Simulink. Here, fuzzy logic controller using Mamdani approach is applied to control the MBC 500 magnetic bearing system and the performance of the controlled system will be analyzes using Matlab/Simulink. At the end of the project, a fuzzy logic controller system using Mamdani approach which is able in stabilizing the position of the rotor for magnetic bearing system will be design.
