【 摘 要 】

Aiming at the inaccuracy of the magnetic model parameters in the magnetic levitation flywheel's unbalanced vibration control algorithm, this paper proposes an online closed-loop identification method for the magnetic parameters, and feeds the identification results back to the unbalanced vibration control algorithm to obtain higher vibration control precision.
