| Abstract: |
| 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. |
