摘要：A magnetically suspended flywheel (MSFW) always suffers from rotor mass imbalance disturbances, which result in synchronous vibration forces and affect the high precision control. The synchronous vibration forces in MSFW are mainly comprised of current stiffness forces and displacement stiffness forces. In this paper, a lead feedforward compensation method is proposed to simultaneously suppress the two stiffness forces. First, the dynamical model of the synchronous vibration forces and the phase lag influence of the power amplifier on the displacement stiffness forces are given. Then, the principle and implementation of the proposed method used for synchronous vibration forces complete suppression are analyzed. The performance comparison between the conventional scale compensation method and the proposed lead feedforward method is investigated. Simulation and experimental results on a MSFW demonstrate the effectiveness and superiority of the proposed synchronous vibration forces suppression method. © 2018
