The algorithm, which is based on a simple linearised magnetic force equation, utilises three kinds of measured signals, i.e. rotor displacement, control current and magnetic force. The simulation and Experimental results show that the proposed algorithm is very simple and effective in adaptively identifying the current and position stiffnesses of the AMB.
