    • LTI modelling of active magnetic bearings by means of system identification 

      Van Schoor, George; Van Vuuren, Pieter Andries; Venter, Willem Christiaan (SAIEE Publications, 2011)
      A relatively unknown phenomenon in active magnetic bearings (AMBs) is that the frequency content of their rotor position signal can induce nonlinear behaviour in the bearings. The existence of such frequency-induced nonlinear ...

    • μ-Analysis applied to self-sensing active magnetic bearings 

      Van Schoor, George; Van Vuuren, Pieter Andries (SAIEE Publications, 2011)
      The stability margin of a two degree-of-freedom self-sensing active magnetic bearing (AMB) is estimated by means of ?-analysis. The specific self-sensing algorithm implemented in this study is the direct current measurement ...
