摘　　要：无轴承永磁薄片电机转子质量的不平衡振动严重影响了系统的动态特性及安全运行。介绍了无轴承永磁薄片电机转子悬浮力产生机理,推导了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,对无轴承永磁薄片电机转子进行了振动补偿控制,设计了反馈不平衡补偿控制系统,采用Matlab/Simulink工具箱构建了仿真系统,进行了性能仿真试验。研究结果表明:基于反馈补偿控制器的振动控制策略能够较好的抑制悬浮转子振动,大大提高了转子的旋转精度。The rotor＇s unbalance mass vibration of a bearingless permanent magnet slice motor impacts on the dynamic properties and stable function. The suspension principle of a bearingless permanent magnet slice motors was introduced, and dynamics equations of the rotor were deduced. The rotor vibration control on the bearingless permanent magnet slice motor was completed based on the decoupling control of the electromagnet torque and radial suspension forces, and unbalance feedback compensation method was designed. The control system was established and performance simulation was accomplished with Matlab/Simulink toolbox. The research results have shown that the rotor vibration amplitude can be reduced and the rotation precision of the rotor can be improved greatly.
