Description

technical field

[0001] The invention relates to a highly reliable, integrated, and low-power consumption digital control device for a magnetic bearing of a magnetic levitation flywheel, which is used for controlling magnetic bearing systems such as a magnetic levitation flywheel, and is suitable for applications such as high reliability, high integration, and low power consumption , especially suitable for aerospace and space applications. Background technique

[0002] The flywheel is the basic attitude control actuator on small and medium-sized satellites. Compared with the traditional mechanical bearing flywheel, the magnetic levitation flywheel has the advantages of no contact, no friction, no lubrication, high precision, long life, etc., so it has broad application prospects in satellites.

[0003] The existing maglev flywheel controllers are divided into two categories: analog controllers and digital controllers. The analog controller has the disadvantages of large po...
