Intelligent control of enameled wire spot welding based on pattern recognition PI self-tuning
The time of enameled wire spot welding process is short,requiring quick response of spot welding power in control. The electrodes of this welding,with the characteristics of large difference in properties and constant loss during the use,need to be replaced frequently. It is difficult to make selfadaptive adjustment according to the difference of spot welding circuits,especially in electrodes,due to that the parameters of conventional PID control are constant. In this paper,an intell-igent control method of enameled wire spot welding based on pattern recognition PI self-tuning is proposed to solve this problem. The results show that compared with the conventional PID control method,the control parameters can be self-tuning for different electrodes,which improves the stability and rapi-dness of enameled wire spot welding control and obtains a good effect in application.
