摘要：

A　＇damping　loop＇　control　strategy　consisting　of　the　external　loop　of　voltage　regulation　and　the　internal　loop　of　current　regulation　and　an　extra　＇damping　loop＇　for　wire　feeding　motor　of　submerged　arc　welding　is　proposed.　Different　dual　closed-loop　control　system　is　implemented　according　to　varied　welding　code.　The　H-bridge　bipolar　reversible　PWM　speed　regulation　system　is　applied　in　power　circuit,　which　principles　are　analyzed.　The　dual　closed-loop　block　is　established　and　the　＇damping　loop＇　of　the　speed-varying　wire　feeding　is　also　expounded.　The　good　dynamic　and　static　performance　of　the　wire　feeding　system　with　this　control　strategy　is　verified　by　actual　results.　©　2012　IEEE.
