For on-line identi"cation of the current and position sti!nesses in an active magnetic bearing (AMB) system equipped with four pairs of built-in radial magnetic force transducers, a modi"ed least-mean-squares (LMS) algorithm is proposed. The algorithm, which is based on a simple linearised magnetic
