Research of synchronous control of flying-type welder

According to the traveling behaviors of a flying-type flash-butt welder and billets being rolled in an EBROS (Endless-bar Rolling System), a composite PID controller based on a single neural-cell network was used in the welder driving system to improve its dynamic and static properties, and strength its tracking performance to the billet being rolled. An artificial immune feedback law was introduced into the system to reduce the disturbances from its outside and inside. The simulation results indicate that the introduction of a feed-forward PD corrector into the welder controller can increase the welder tracking precision, and the artificial immune feedback law can not only strengthen the power for the welder to withstand the outside disturbances, but also improve its self-adaptive performance.
