Abstract

Conical-shape magnetic bearings are currently a potential candidate for various magnetic force-supported applications due to their unique geometric nature reducing the number of required active magnets. However, the bearing structure places control-engineering related problems in view of underactuated and coupling phenomena. The paper proposes an Adaptive Disturbance Rejection Control (ADRC) for solving the above-mentioned problem in the conical magnetic bearing. At first, virtual current controls are identified to decouple the electrical sub-system, then the active disturbance rejection control is employed to eliminate coupling effects owing to rotational motions. Comprehensive simulations are provided to illustrate the control ability.

基于主动抗扰控制的圆锥磁悬浮轴承抗耦合方法

锥形磁性轴承目前是各种磁力支持应用的潜在候选者，因为其独特的几何特性减少了所需的主动磁体的数量。然而，鉴于欠驱动和耦合现象，轴承结构存在与控制工程相关的问题。针对圆锥磁悬浮轴承的上述问题，提出了一种自适应抗扰控制方法。首先，识别虚拟电流控制来解耦电气子系统，然后采用主动抗扰控制来消除由于旋转运动引起的耦合效应。提供了全面的仿真来说明控制能力。

期刊介绍： Acta Polytechnica is a scientific journal published by CTU in Prague. The main title, Acta Polytechnica, is accompanied by the subtitle Journal of Advanced Engineering, which defines the scope of the journal more precisely - Acta Polytechnica covers a wide spectrum of engineering topics, physics and mathematics. Our aim is to be a high-quality multi-disciplinary journal publishing the results of basic research and also applied research. We place emphasis on the quality of all published papers. The journal should also serve as a bridge between basic research in natural sciences and applied research in all technical disciplines. The innovative research results published by young researchers or by postdoctoral fellows, and also the high-quality papers by researchers from the international scientific community, reflect the good position of CTU in the World University Rankings. We hope that you will ﬁnd our journal interesting, and that it will serve as a valuable source of scientiﬁc information.
