Research on Adaptive Controller for Variable Polarity Plasma Arc Welding Power Supply with High-Frequency

Aiming at the problem of output current waveform distortion caused by superimposed high frequency components in the output current of varying polarity of VPPAW power supply. A novel adaptive PID controller with automatic switching is introduced in this paper, and the controller is established based...
