摘　　要：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。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.
