This investigation deals with a small flywheel energy storage rotor supported by active magnetic bearing system. In order to reduce the energy consumption of this system, we designed the sliding mode controller, the backstepping controller, the H-infinity controller and the switching type PID controller without using bias current based on a simple rigid model which is derived by superposition principle. On the other hand, in oder to obtain a higher density of energy and get rid of the influence of the first bending mode which leads to the system unstable, a flexible model based on finite-element method is also derived. Thereafter, we proposed making a mode separation using singular value decomposition method when the gyroscopic matrix is considered in the equation of motion. Further, the reliability of reduced-order FEM model is verified and the five H_∞controllers are designed to guarantee the whole stability up to 200Hz. The effectiveness of the reduced-order flexible model and the stability of the closed-loop system are verified by simulations and experiments. Also, we have succeeded to pass through the critical speeds about the two rigid mode critical speeds including a forward and a backward whirl, and the backward mode critical speed of the first bending critical speed. Also, the gyroscopic effect has been completely compensated. The trajectory orbits were quite stable without backward whirl.

研究了一种由主动磁轴承系统支撑的小型飞轮储能转子。为了降低系统的能耗，基于叠加原理导出的简单刚性模型，设计了不使用偏置电流的滑模控制器、反步控制器、h∞控制器和开关型PID控制器。另一方面，为了获得更高的能量密度，消除导致系统不稳定的一阶弯曲模态的影响，还推导了基于有限元法的柔性模型。在此基础上，提出了在运动方程中考虑陀螺矩阵的情况下，采用奇异值分解方法进行模态分离。进一步验证了降阶有限元模型的可靠性，设计了5个H_∞控制器，保证了系统在200Hz范围内的整体稳定性。仿真和实验验证了该降阶柔性模型的有效性和闭环系统的稳定性。此外，我们还成功地通过了向前和向后旋转两种刚性模态临界速度的临界速度，以及第一弯曲临界速度的向后模态临界速度。同时，陀螺效应也得到了完全补偿。轨道轨道非常稳定，没有反向旋转。
