摘要： 通过建立三轴转台的动不平衡模型，得出转台存在多周期扰动力矩。该多周期扰动力矩与转台三轴转速有关，影响转台的定位精度、位置精度和速率精度。为抑制三轴转台系统的扰动力矩，提出多周期有限维重复控制方法，并证明该方法能消除多周期扰动引起的转台系统误差。仿真结果表明多周期有限维重复控制可以有效地抑制转台系统存在的动不平衡扰动。

Abstract: The turntable having multi-period disturbance torque is obtained by setting up the dynamic unbalance model of three-axis turntable. The multi-period disturbance torque is related to three-axis rotate speed of turntable and influences localization precision, position precision and speed precision of turntable. In order to attenuate system disturbance torque of three-axis turntable, the method of multi-period finite-dimensional repetitive control is proposed and proves to be a success in attenuating the systematic error of turntable caused by multi-period disturbance. The result of simulation shows that multi-period finite-dimensional repetitive control can attenuate dynamic unbalance disturbance of turntable system effectively.

Key words: Dynamic unbalance Multi-period disturbance Finite-dimensional repetitive control, Three-axis turntable
