| Abstract | There are a lot of interference sources in the system of the arc welding inverter power. In this paper, a small-signal model which was built by the method of state-space average was quoted. A control system which comprised an interference of load resistance and an interference of power supply fluctuation was built. A H2/H∞state -feedback controller was designed in the method of LMI. The simulation indicated the result, which the interference of power was measured by H2 norm so that the output of the system was influenced weakly, and the interference of arc load was measured by H∞ norm so that the system was robust. |
