A Magnetic Bearing Wheel (MBW) with inclined magnetic poles is under development. This paper deals with fine tuning of the magnetic bearing controller. In general, it is very difficult to identify disturbance factors of the magnetic bearing, and no model-based controller can achieve sufficiently low disturbance condition. In this paper, it is shown that all disturbance factors can be accurately identified using displacement sensor output and electromagnet current in the low disturbance condition realized by the disturbance feedback controller in our 3rd report. In addition, if the results of disturbance factors are applied to the magnetic bearing controller, only the magnetic bearing controller can greatly decrease disturbance of MBW without additional disturbance sensors.
