Design of Intelligent Loading System for Electromagnetic Coil Device Based on EtherCAT

In order to solve the problems such as not being able to be co-supported and co-controlled for many kinds of large loads and fast reloading, the intelligent loading system of electromagnetic coil device was designed and researched, and the accurate adaptive position control design was carried out for the loading end point of the intelligent loading system. The real-time location of the launcher's body tube is detected by laser ranging technology, and the data is calculated and converted by EtherCAT real-time industrial Ethernet to complete the real-time online correction of the loading endpoint of the intelligent loading system. The adaptive trajectory planning of the intelligent loading system is realized by combining PLC trajectory planning technology. The results show that the intelligent loading system can realize automatic loading with large load and high speed under the double S-type trajectory planning based on adaptive control. In the study, the end point feedback and the end point command value track well during each loading. The application of EtherCAT network technology and laser ranging technology in the field of automatic filling was expanded, which provided theoretical guidance for the subsequent development of automatic filling control system.
