One of the performance-limiting factors in the design of robust controllers for active magnetic bearing systems is the fact that the controller needs to be robust to the gyroscopic effects, that is rotational speed-dependent dynamics of the system. Studies in the literature show that better performance and stability can be achieved when gyroscopic effects are explicitly handled by a cross-feedback control for rigid rotor-active magnetic bearing systems. For flexible rotor-active magnetic bearing systems, gyroscopic effects are mainly dealt by defining the rotational speed as an uncertain parameter of the model or with linear parameter-varying controllers. This study explores the novel idea of compensating gyroscopic effects of a flexible rotor-active magnetic bearing system with an add-on controller and investigates its effects on the achieved performance of μ-controllers. The study is carried out on an experimental active magnetic bearing test rig with relatively high gyroscopic effects. An add-on controller is designed to compensate the gyroscopic effects of the first and second flexible modes of the rotor. Two μ-controllers are designed for the system: (1) benchmark controller that is designed using a standard control approach for active magnetic bearing systems and (2) controller designed with a modified model of the system in which the gyroscopic effects for the first and second flexible modes are reduced because of the presence of the add-on controller. Both controllers are implemented, and their performances are compared for initial levitation, run-up test from 0 to 10,000 r/min, orbit sizes at various speeds, and the computational cost of implementing each controller. The results suggest that better performance is potentially possible at the cost of significant increase in the computational complexity of the controller.

有源电磁轴承系统的鲁棒控制器设计中的性能限制因素之一是，控制器需要对陀螺效应具有鲁棒性，即系统的转速依赖于动力学。文献研究表明，通过刚性转子-主动式磁悬浮轴承系统的交叉反馈控制来明确处理陀螺效应，可以获得更好的性能和稳定性。对于柔性转子-主动磁轴承系统，陀螺效应主要通过将转速定义为模型的不确定参数或使用线性参数变化控制器来解决。μ-控制器。该研究是在具有较高陀螺效应的实验性主动磁轴承试验台上进行的。附加控制器设计用于补偿转子的第一和第二柔性模式的陀螺效应。两个μ-控制器是针对以下系统而设计的：（1）使用主动磁轴承系统的标准控制方法设计的基准控制器，以及（2）使用修改后的系统模型设计的控制器，其中第一和第二柔性陀螺效应由于附加控制器的存在，减少了各种模式。两种控制器均已实现，并针对初始悬浮，从0到10,000 r / min的启动测试，各种速度的轨道大小以及实现每种控制器的计算成本进行了比较。结果表明，以显着增加控制器的计算复杂度为代价，可能有可能实现更好的性能。
