지능제어 알고리즘을 이용한 펄스 인버터 TIG 용접기의 성능 향상

Pulse inverter-type TIG(Tungsten Inert Gas) arc welders are studied to investigate the dynamic performance of welding. Welding currents are controlled to be pulse waveforms, resulting in stable arc and better welding performance, The hybrid-type controller is proposed to control the welding current. To demonstrate the practical significance of our results, we present some simulation results.
