Problems solved by technology

However, from the perspective of reliability, this method has great potential safety hazards. The inventor found that when the magnetic suspension bearing system fails, if the magnetic suspension bearing system is first controlled to stop the shaft suspension, and then the motor is controlled to stop the rotation, it is easy to make the The shaft is frictionally rotated under the drive of the motor

Abstract

The invention discloses a control device for a magnetic suspension bearing system. The control device for the magnetic suspension bearing system comprises a magnetic suspension bearing controller used for controlling a bearing in the magnetic suspension bearing system, and a motor controller used for controlling a motor in the magnetic suspension bearing system, wherein the motor controller is further used for controlling the motor for stopping rotation when the magnetic suspension bearing system is in fault, and the magnetic suspension bearing controller is further used for controlling stopping shaft suspension of the magnetic suspension bearing system after the motor is controlled by the motor controller for stopping rotation. Through the control device, the magnetic suspension bearing system in fault is prevented from being further damaged.

Description

technical field [0001] The invention relates to the field of control, in particular to a control device for a magnetic suspension bearing system. Background technique [0002] The magnetic suspension bearing technology has the advantages of no oil, no friction and low loss. In the magnetic suspension bearing system, the control of the magnetic suspension bearing and the motor control are inseparable. Only when the motor is driven by the shaft can the shaft rotate without friction. [0003] The magnetic suspension bearing system includes the magnetic suspension bearing controller and the motor controller. Since the magnetic suspension bearing controller and the motor controller have great differences in the controller principle and hardware structure, in the prior art, when designing the magnetic suspension bearing system, the The two controllers are designed separately, and the general block diagram is as attached figure 1 shown. figure 1 Among them, DSP1' is the motor con...
