摘要

摘要: 多转子系统在运行过程中，往往需要保持各个转子的运动同步，以达到最佳的性能与输出效果。对于转子系统，设计了一种以支承响应作为输入的控制方法，实现了两个转子系统之间的完全同步。这种同步，在支承受到随机干扰和故障产生的脉冲干扰下，仍然能够保持很好的稳健性。首先对同步控制方法进行了理论分析与证明，然后以弹性支承悬臂转子为对象，进行了仿真验证。模拟实际基础激励，在支承处施加随机与脉冲载荷，仿真结果证明了同步的稳定性，并且达到了很高的精度。

Abstract: In this paper we addressed the dynamical synchronization between rotors and its robustness for random and pulse disturbances. For a dual-rotor system, we present a control method to realize synchronization between the rotors, which only needs the dynamic response of an elastic support of a rotor. The control method for synchronization by support coupling is proved theoretically. For validation an overhung rotor with two elastic supports were simulated. To examine the robustness of the method, additional pulse and stochastic disturbance forces are exerted on one of the two supports respectively. The results show that the simulation system will reach synchronization with the rotor rapidly. The responses of supports and disks prove that a high accuracy can be attained even under disturbances.
