Abstract: To overcome the shortcomings of traditional base isolation technology， such as non-adjustable isolation parameters， limited low-frequency isolation effect， and inability to achieve vertical isolation， magnetic levitation technology is introduced to design a magnetic levitation vibration isolation bearing. The relationships between the levitation force of the electromagnet and the coil current and levitation gap are analyzed. The nonlinear model of the magnetic levitation vibration isolation bearing is established. Combining the advantages of terminal sliding mode and super-twisting algorithm and introducing an adaptive law to adjust the coefficients in the super-twisting algorithm， an adaptive super-twisting terminal sliding mode control strategy is proposed. Through experimental verification， the proposed control scheme can suppress the chattering phenomenon in the traditional sliding mode control， with high control accuracy and good steady-state and dynamic performance. The magnetic levitation vibration isolation bearing has excellent stability and disturbance-resisting performance.
