Permanent magnetic bearing and the hydrodynamics spiral groove bearing are utilized as supports for the energy storage flywheel rotor system. The rotor dynamics of flywheel energy storage system with a hybrid permanent magnetic mechanical bearing is studied. The kinetic energy, potential energy and the energy dissipation functions of the whole system are obtained, and the rotor equation of motion is derived by using Lagrange Maxwell's equation, the analytical solution of the equation is obtained by using state vector method. The critical speed, modal damping, and the amplitude frequency characteristics are simulated. Based on the numerical simulation, the dynamic parameter of flywheel rotor system is optimized. A flywheel energy storage system is developed, which can arrive at 48 000 r/min and store the energy of 0.3kWh. Experimental result shows that the system can run up to the designed speed steadily, the dynamic characteristics is in agreement with the theoretical one.

A control method, crossfeedback control, is studied to restrain gyroscopic effect of a magnetic bearingsupported flywheel system. The stability of the system is analyzed under crossfeedback control. The results show that the gyroscopic effect could be restrained by using this method and the system keeps stable when the rotation speed is over some critical value which is relative to the moments of inertia of the rotor and could be adjusted by the parameters of the controller according to the requirements of applications. The performance of this system with crossfeedback control is analyzed by experiments and compared with that under decentralized proportional integral differential (PID) control only. The experiments show that the system under decentralized PID control is unstable at 12 000 r/min, while that with crossfeedback control is still work normally at 25 000 r/min. Therefore, this method could restrain the gyroscopic effect effectively.

To make a rotor running at a high rotational speed, its nutation and precession modes should be restrained effectively. But for such a rotor, traditional PID controllers are not suitable any more. A method called magnetic force lead control is created to restrain the nutation mode of a flywheel rotor. And a displacement...

For a magnetic-bearing-supported high-speed flyw-heel with significant gyroscopic effects, its nutation and precession modes greatly influence stability of a system at high rotational speeds. To make a rotor running at a high rotational speed, its nutation and precession modes should be restrained effectively. But for such a rotor, traditional PID controllers are not suitable any more. A method called magnetic force lead control is created to restrain the nutation mode of a flywheel rotor. And a displacement cross feedback with a low-pass filter is added to restrain the precession mode. Analysis results, simulation results and some experimental results about the method are provided. They all show the effects of the method.

对于具有强陀螺效应的磁悬浮飞轮系统,在实际运行时其章动与进动模态会对转子高速下的稳定性产生影响,必须有效地对其进行抑制,以使磁悬浮飞轮系统运行到工作转速。传统的PID控制已经难以满足系统的要求。给出了一种新的抑制磁悬浮飞轮章动的方法——电磁力超前控制。这种方法结合位移交叉能同时对章动与进动进行抑制,并且实现简单。对方法的有效性进行了理论分析,并给出了仿真结果及部分试验数据。
