The primary crystal of molten metal is one of the important links in the process of spot and seamwelding joint. 熔核的一次结晶是点缝焊接头形成过程中的重要环节之一。
This paper presents a kind of practical discrete MRAC scheme forthe welding squeezing force adaptive control in the longitudinal seamwelding tube mill with high frequency. 为了实现高频直缝焊管焊接挤压力自适应控制,本文提出了一种实用的离散模型参考自适应控制系统(MRACS)的控制方案。
