Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of magnetic suspension, and in particular relates to a magnetic suspension bearing control method, device, storage medium and magnetic suspension system, in particular to a magnetic suspension bearing control method, device, storage medium and magnetic suspension system. Background technique [0002] Magnetic levitation technology can use magnetic force to overcome gravity to levitate objects. The magnetic levitation shaft runs in a non-contact environment and can easily achieve high-speed rotation. Magnetic levitation compressor is a common magnetic levitation rotating machine, which has been applied in many occasions. The magnetic levitation compressor is composed of two core components, the motor and the magnetic levitation bearing. The bearing coil current is adjusted in real time by the bearing controller to realize the stable levitation of the motor rotor and keep no mechanical contact between the rot...
