The present invention relates to a magnetic suspension reaction flywheel open-loop high-accuracy unbalanced vibration control system. It includes the following several portions: displacement sensor, displacement signal interface circuit, rotating speed detection device, magnetic bearing controller, magnetic bearing power amplification drive circuit and flywheel position identification device. The magnetic bearing controller includes axial bearing controller and radial bearing controller, the radial bearing controller is formed from two portions of stabilization controller and unbalanced vibration controller, in which the unbalanced vibration controller can be used for making compensation for displacement feedback of stabilization controller.
Description
technical field [0001] The invention relates to an open-loop high-precision unbalanced vibration control system for a magnetic suspension reaction flywheel, which is used for high-precision control of the magnetic suspension reaction flywheel and rotor vibration control. Background technique [0002] With the development of magnetic bearing technology, the research of magnetic levitation flywheel technology has been paid more and more attention by various countries. Magnetic suspension flywheels can be divided into magnetic suspension bias momentum wheels and magnetic suspension reaction flywheels according to the rated speed. Among them, the magnetic suspension bias momentum wheel works near a higher rated speed (such as above 20000 rpm), while the magnetic suspension reaction flywheel has a lower rated speed (such as below 10000 rpm), and the flywheel works in a lower speed range. [0003] The flywheel of traditional mechanical bearings is supported by ball bearings. The ...
