The financial industry reported on May 11, 2024 that according to an announcement from China State Intellectual Property Office, Zhuhai Gree Electric Co., Ltd. has applied for a patent application called "A magnetic bearing control method, device, medium, electronic equipment and system" The patent, publication number is CN118011788A, and the application date is December 2023.

The patent summary shows that the application discloses a magnetic bearing control method, device, medium, electronic equipment and system, which are suitable for the field of magnetic bearing control. This method is based on the traditional second-order linear active disturbance controller, and introduces the extreme learning machine model, the support vector machine model and the random forest model to obtain the prediction output, and combines the predicted disturbance with the observed disturbance and then inputs it back to the second-order linear active reaction. disturbance controller to control the target input of the electromagnetic bearing rotor. Compared with traditional methods, this technology effectively avoids the problem of extended observers when observing large loads through joint input of multiple models. This method not only takes into account observed disturbances, but also fully considers predicted disturbances, improving the precision and accuracy of control.
