Modeling and simulation of decoupling control system of aluminum pulsed MIG welding

  • Received Date: July 15, 2007
  • In aluminum pulsed MIG welding, too much coupled welding parameters influence the stabilization of control sy stem of welding process.In order to solve above problem, the multi-input multi-output (MIMO)control model of aluminum pulsed MIG welding was presented.Based on thisMIMO model, a neural network inverse plant decoupling control system with the neural network PID controller was designed to control welding process.The structure and the principle of this control system were given, and the characteristics of control system were analyzed.The simulation results show that the satisfied dynamic and static performance had been obtained.It provides the theoretical basis to realize the process control in aluminum pulsedMIG welding.
