摘要:
在旋转机械中,由于转子质量的不平衡会导致沿旋转方向的振动,严重影响了系统的动态特性及安全运行,特别是对具有较高速度的悬浮转子来说,不平衡补偿具有重要的现实意义。该文介绍了悬浮转子振动控制原理,推导出悬浮转子的动力学方程。在电磁转矩和径向悬浮力解耦控制的基础上,对无轴承永磁同步电机转子进行了振动补偿控制,基于前馈法设计了不平衡补偿控制系统,并利用Matlab中Simulink工具箱对该系统进行了仿真试验研究。结果表明:基于前馈补偿控制器的振动控制策略能够很好的抑制悬浮转子振动,提高了转子的旋转精度。 |

Abstract:
The vibration originated from the rotor's unbalance mass impacts on the dynamic properties and stable function badly. So unbalance compensation on the rotating machine has important practical meaning, especially in the case of suspended spindle. A mass unbalance compensation technique is presented to reduce the unbalance vibration of suspended spindle. Dynamics equation of spindle is deduced. The spindle vibration control of the bearingless permanent magnet synchronous motor is achieved based on the decoupling control of the electromagnet torque and radial suspension forces. The control system is simulated with Matlab/Simulink toolbox. The simulation results have shown that the control system can reduce the spindle vibration and this method can improve the rotation precision. |
