Abstract: Firstly, the paper brings forward the structure of the designed control system,
meanwhile carries through the design of the hardware circuit of the system. Secondly, the paper illustrates the design process of the fuzzy controller through detailed analysis on the structure of fuzzy control system. Lastly, through the establishment of the producing the mathematical model of the SVPWM wave, the method on how to realize the frequency control system by using DSP device is educed. The constant pressure system possesses remarkable characteristics, such as quick response, good reliability, auto constant pressure, etc.
