A magnetic bearing system and its control method, device, storage medium and processor

Abstract

The invention discloses a magnetic bearing system and its control method, device, storage medium and processor. The method comprises: using observation equipment to observe the total disturbance of the magnetic bearing system to obtain the observation disturbance of the magnetic bearing system; and, using a prediction model, predicting at least part of the disturbance of the magnetic bearing system to obtain the predicted disturbance of the magnetic bearing system; and determining the control amount of the magnetic bearing system according to the observed disturbance and the predicted disturbance The control quantity of the magnetic bearing system controls the suspension displacement of the bearing rotor; wherein, the control quantity of the magnetic bearing system is the control quantity of the bearing rotor by controlling the bearing coil with one degree of freedom. In this scheme, the control variables of the magnetic bearing system are compensated based on the total disturbance and predicted disturbance observed by the magnetic bearing system to meet the displacement accuracy requirements of the magnetic bearing system.

Description

technical field [0001] The invention belongs to the technical field of magnetic levitation, in particular to a magnetic bearing system and a control method, device, storage medium and processor thereof, and in particular to a random forest optimized electromagnetic bearing control method, device, magnetic bearing system, storage medium and processing device. Background technique [0002] In the control process of the magnetic bearing system, the selection of the controller is very important. Selecting a reasonable controller can make the bearing rotor stably levitate, and the control accuracy of the rotor levitating displacement is high. [0003] In the related scheme, when a PID (proportional-integral-derivative) controller is selected as the controller of the magnetic bearing system, the anti-interference ability of the PID controller is weak and cannot meet the displacement accuracy requirements of the magnetic bearing system. [0004] The above content is only used to a...
