Wire extension sliding model control based on rapid prototyping in aluminum alloy pulsed MIG welding

According to the stability problem of wire extension in aluminum alloy pulsed MIG welding, a rapid prototyping control platform using the xPC real-time target environment based on the sliding mode control theory was established, and then the real-time control on wire extension in aluminum alloy pulsed MIG welding was carry out with sliding mode controller. The results show that the sliding mode controller can control the wire extension accurately in aluminum alloy pulsed MIG welding and the rapid sliding model prototyping system has strong robustness on external disturbance and system parameters perturbation.
