Abstract:This paper presents an improved plasma arc model on basis of the famous Mayr arc model and Cassie arc model. Additional parameters is added to the proposed arc model to enable the model take into account not only the arc heater's electrical characteristics under stable working conditions, but also the disturbance aroused by the mass flow wave. In addition, the transition function between the Mayr arc model and Cassie arc model is discussed to develop a better model. The arc model is established in Matlab/Simulink by S-Function and the whole arc heater power system is test implemented with an 18 pulse rectifier and the arc load. The considerable degree of correspondence between the simulated and experimental results demonstrates that this arc model can describe both static and dynamic characteristics with high accuracy.
