Description
Summary:The multi-source oscillation of magnetic levitation permanent magnet motor (ML-PMM) under high speed operation is inevitable. The reasons are the influence of the strong coupling characteristics of high speed permanent magnet motor(HSPMM), the nonlinear characteristics of power converter and the coupling characteristics of magnetic levitation control system. Aiming at the multi-source oscillation caused by magnetic levitation system and HSPMM, the multi-source oscillation suppression control method suitable for magnetic levitation-high speed permanent magnet motor(ML-HSPMM) is studied in this paper. The stability of ML-HSPMM and the small signal model of the motor are analyzed. Finally, the control strategy of is verified by simulation and experiment.
