Plasma flow control, as a novel active flow control technique, has become a newly-rising focus in the international aerodynamics and aerothermodynamics fields. The character and research status quo of plasma aerodynamic actuation modeling are introduced in the paper. A detail specification of four basic models of plasma aerodynamic actuation is discussed. The simulation technologies, the merits and defects of the methods are discussed. The development direction of plasma flow control is analyzed. More researches based on particle simulation will be developed in the future. More and more factors, such as the unsteady characteristic of plasma aerodynamic actuation, will be considered in modeling, which makes the simulation model much more accord with the physical process. Researches of higher inflow velocity will be carried on to meet the application demand. The deep simulation research is a help to revealing the physical essence of plasma aerodynamic actuation and its interplay with boundary layer .so as to promote the research and development of plasma flow control technology in our country.
