A new anti-vibration algorithm for active magnetic bearings application

Among the advantages of active magnetic bearings, the absence of contact, the lifetime and the safety (failure detection) can be put forward. This paper presents a new algorithm for unbalance control for active magnetic bearings applications. Contrary to other methods, this new algorithm can work on the whole range of rotational speed while preserving the stability. A systematic tuning approach based on a global model has been developed and is presented here. This algorithm has been implemented on various applications. An example of application on an air compressor is presented here.
