| 目的 为提高包装生产线纠偏机构控制精度，改善产品外观，提高产品合格率，结合转矩观测器和积分型滑模变结构算法设计一种纠偏装置控制系统。方法 在分析纠偏装置结构的基础上，以纠偏伺服电机为研究对象，提出一种电机控制方法。负载转矩观测器和积分型滑模控制器不但可以解决负载扰动对控制系统性能的影响，而且可以减小滑模控制器的抖振幅度，饱和函数则可以进一步减小系统抖振。通过实验验证所述方法的可行性和有效性。结果 实验结果表明，所述控制方法基本无超调量，达到稳定状态约耗时0.5 s;采用所述纠偏装置，包装薄膜跑偏量最大值只有0.70 mm，包装合格率均在97%以上。结论 在保证产品质量前提下，纠偏装置鲁棒控制系统可以提高产品合格率和包装生产线工作效率。 |

| The work aims to design a control system of the rectifying device combining torque observer and integral sliding mode variable structure algorithm to improve the control precision of the rectifying mechanism of packaging production line, and improve the appearance and qualified rate of product. On the basis of analyzing the structure of rectifying devices and taking rectifying servo motor as the research object, a motor control method was put forward. The load torque observer and the integral sliding mode controller could not only solve the effect of load disturbance on the performance of the control system, but also reduce the chattering amplitude of the sliding mode controller. In addition, the saturation function could further reduce the system chattering. The feasibility and effectiveness of the proposed method were verified by experiments. The experimental results showed that the control method basically had no overshoot, and it took about 0.5 s to reach the stable state. By adopting the rectifying device, the maximum deviation amount of the packaging film was only 0.70 mm, and the qualified rate of the packaging was above 97%. On the premise of ensuring product quality, the robust control system of rectifying devices can improve the qualified rate of products and the working efficiency of packaging production lines. |
