目的 为了解决包装过程中薄膜纵向跑偏，以及常规控制方法性能较差等问题。方法 基于模糊控制设计一种包装膜自动纠偏系统。分析包装薄膜跑偏的原因，并给出自动纠偏装置结构。在此基础上，建立纠偏系统数学模型，同时设计一种模糊控制器。利用 MCF52235 嵌入式芯片给出控制器的硬件结构。最后进行试验验证。结果 跑偏量绝对值的最大值仅为 0.4 mm，满足包装工艺控制要求。结论 所述模糊控制方法能够有效地改善系统纠偏能力，具有较好的动态响应性能。

The work aims to solve the problems like films' longitudinal deviation and poor performance of conventional control methods in the packaging process. An automatic correction system of packaging films was designed based on fuzzy control. The reasons for packaging film deviation were analyzed and the automatic correction device structure was also given. On this basis, the mathematical model of correction system was established and a fuzzy controller was designed. The hardware structure of the controller was presented by MCF52235 embedded chip. Finally, the test verification was carried on. The maximum absolute value of deviations was only 0.4 mm and it could satisfy the requirements of packaging process control. The proposed fuzzy control method can effectively improve system correction ability and it has better dynamic response performance.
