The invention discloses a magnetic levitation bearing control method and device, a storage medium, and a magnetic levitation system. The method comprises the following steps of determining whether thestarting torque required when a compressor in the magnetic levitation system is started exceeds preset torque or not; and if the starting torque required when the compressor is started exceeds the preset torque, increasing control parameters of the magnetic levitation system to control the control parameters of a magnetic levitation bearing to be adapted to the starting torque required when the compressor is started. According to the scheme disclosed by the invention, the problem that the starting torque is variable to affect the starting reliability can be solved so as to achieve the effectof improving the starting reliability. 本发明公开了一种磁悬浮轴承控制方法、装置、存储介质及磁悬浮系统，该方法包括：确定磁悬浮系统中压缩机启动时所需要的启动转矩是否超过设定转矩；若压缩机启动时所需要的启动转矩超过设定转矩，则增大磁悬浮系统中磁悬浮轴承的控制参数，以控制磁悬浮轴承的控制参数适应于压缩机启动时所需要的启动转矩。本发明的方案，可以解决由于启动转矩不定而影响启动可靠性的问题，达到提升启动可靠性的效果。
