Furthermore, in this study, we designed an adaptive controller based on the RBF neural network for the rotating magnetic bearing, which can improve the pointing accuracy of satellite loads. To begin, the advanced features of the new platform are described in comparison with the traditional electromechanical platform, and the structural characteristics and working principle of the platform are clarified. The significance of rotating magnetic bearings in improving load pointing accuracy is also clarified, and its rotor dynamics model is established to provide the input and output equations. The adaptive controller based on the RBF neural network is designed for the needs of high accuracy of the load pointing, high stability, and strong robustness of the system, and the current feedback inner loop is added to improve the system stiffness and rapidity. The final simulation results show that, when compared to the PID controller and robust sliding mode controller, the controller\u2019s pointing accuracy and anti-interference ability are greatly improved, and the system robustness is strong, which can effectively improve the pointing accuracy and pointing stability of the satellite\/payload, as well as provide a powerful means of solving related problems in the fields of laser communication, high score detection, and so on.<\/jats:p>","DOI":"10.3390\/s23208543","type":"journal-article","created":{"date-parts":[[2023,10,18]],"date-time":"2023-10-18T10:36:56Z","timestamp":1697625416000},"page":"8543","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Rotating Lorentz Force Magnetic Bearings\u2019 Dynamics Modeling and Adaptive Controller Design"],"prefix":"10.3390","volume":"23","author":[{"given":"Feiyu","family":"Chen","sequence":"first","affiliation":[{"name":"Graduate School, Space Engineering University, Beijing 101400, China"}]},{"given":"Weijie","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Aerospace Science and Technology, Space Engineering University, Beijing 101400, China"}]},{"given":"Shengjun","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Aerospace Science and Technology, Space Engineering University, Beijing 101400, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Tan, Z., Luo, R., Li, J., Ling, Q., and Liang, J.
