This study presents a magnetic levitation follow-suspension low-gravity simulation system, aiming to provide new ideas and methods for performance testing experiments of planetary rovers. The system consists of a suspended system and a magnetic levitation system. The former utilizes torque motors and a two-dimensional micro-motion system to provide constant tension, while the latter employs the principle of permanent magnet linear motors to achieve precise position tracking of the planetary rover. The dynamic model is established, and the linearization of the single electromagnetic levitation system is carried out. By introducing current loop feedback and PD control, stable levitation of the single electromagnetic levitation system is achieved. The state equations of the magnetic levitation system are established, and the relationship between the input and output in the frequency domain is obtained through Laplace transformation, demonstrating that the system is a MIMO coupled system. Finally, a cross-coupling control strategy based on adjacent sequential synchronization error is introduced, and a simulation model of the magnetic levitation control system is constructed. The effectiveness of the controller is verified through closed-loop PD control of the single electromagnetic levitation system. The stability of the magnetic levitation system is tested, and the causes of instability are discussed. This study provides valuable insights for further research on creating a low-gravity environment using magnetic levitation.
