In this chapter the advanced mathematical means for computer simulation of aerodynamic control systems of High Voltage Glow Discharge Electron Guns (HVGDEG) current are described and analyzed. The structure of electromagnetic valve for automatic changing the gas pressure in discharge chamber is presented and basic mathematical relations for simulation process of High Voltage Glow Discharge (HVGD) current are given. The mechanical structure of electromagnetic valve (EV) is also presented and analyze if the gas flow has been provided. Also advanced mathematical approach for analyzing such kind of aerodynamic control systems with using Finite Sequence Machines (FSM) Theory and Fuzzy Logic (FL) are described and analyzed. Corresponding practical recommendation for designing and exploitation of such kind control systems are also given.
