| 目的 研究印刷机套准系统耦合建模及精密控制策略以减小套准误差。方法 根据印刷机套准系统工作机理建立多色套准系统的非线性耦合数学模型，并进行线性化改造，在所建立数学模型基础上设计基于PID的前馈套准误差控制策略，并将该策略控制效果与传统PID控制效果进行仿真对比。结果 在张力干扰下，套准误差由±20 μm减小到±0.8 μm；速度波动下，套准误差由±30 μm减小到±1.5 μm。结论 PID前馈控制策略能够显著减小套准误差，提高套准控制的精度。 |

| The work aims to research the coupling modeling and precision control strategy for register system of printing press, so as to reduce register errors. The nonlinear coupling mathematical model of multi-color register system was established according to the register system’s working principle, and the linear transformation was carried out. Based on the linear model, a PID-based feedforward register error control strategy was designed, and the control effect was compared with that of the traditional PID control. Results showed that the register error caused by tension disturbance was reduced from ±20 μm to ±0.8 μm, and the register error caused by velocity disturbance was reduced from ±30 μm to ±1.5 μm. It is concluded that the feedforward PID control strategy can significantly reduce the register error and improve the accuracy of register control |
