Abstract：Aiming at the problem of synchronization performance and suspension air gap accuracy degradation of magnetic levitation platforms for computer numerical control (CNC) machine tools under load disturbance, a ring-coupling synchronous control strategy combining terminal sliding mode was designed, and fuzzy control was used as a synchronization error compensator. The strategy uses a second-order terminal sliding mode control algorithm to achieve stable suspension of the single electromagnetic levitation system. Due to the coupling between the single electromagnetic levitation systems supporting the magnetic levitation platform, a ring-shaped coupling structure based on fuzzy control is designed for synchronous control of real-time synchronization error compensation. The simulation results show that the adopted control scheme effectively reduces the synchronization error of the platform, improves the response speed and accuracy of the suspension platform, and has a strong suppression effect on processing and other disturbances.
