摘要：
An intelligent controller based on Fuzzy controller and expert system (ES) control action for Aluminum alloy Pulsed Metal Inert Gas (Al-P-MIG) welding process is proposed. On the basis of welding pool image vision sensing and processing system, the identification model of welding pool width dynamic response in Al-P-MIG welding process has been setup. And then, in the case that welding pool width reference input value is 3mm, 4mm and 5mm respectively, the PID and Fuzzy control effects are simulated and analyzed. The experiments show that the real-time and precision requirements for detecting and control of weld pool width of AI-P-MIG welding process could be satisfied by the established system.
