•Focus on the high precision synchronous vibration suppression.•Propose a lead feedforward compensation method.•Compensate the residual synchronous disturbances in the displacement stiffness.•Analyze the closed-loop stability. A magnetically suspended flywheel (MSFW) always suffers from rotor mass i...
