The invention provides a high-safety and stable control method for a vehicle-mounted magnetic suspension flywheel battery system based on an interference factor, and the method comprises the steps: solving a difference between a displacement reference signal and an actual displacement signal, and inputting the difference into a Butterworth filter fuzzy active-disturbance-rejection control module to obtain a control current; the control current comprises a radial control current, a torsion control current and an axial control current, the radial control current and the torsion control current are subjected to Clark inverse transformation, the axial control current is subjected to power amplification and then compensated respectively, and three-phase control current of a radial coil and a torsion coil and control current of an axial coil are obtained; on one hand, the control current controls a corresponding coil, and on the other hand, the control current is input into a multi-information extended Kalman filtering prediction module to output an actual displacement signal; and when the dangerous working condition interference occurs, the output signal of the working condition identification and safety judgment module is cut off. According to the invention, the stability, robustness and anti-interference capability of the system can be improved.
