Abstract: The position estimator is a key module of self-sensing active magnetic bearings (AMBs). It can improve system dynamic performance and reduce the axial dimension. Generally, the estimation methods can be divided into two categories: state observer estimation and parameter estimation.

Key words: Synchronous sampling; Direct current estimation; Self-sensing active magnetic bearing
