Study on control strategies for oil-fuel supply system used in supersonic combustion wind tunnel

This paper deals with the operation principle of the oil-fuel supply system used in supersonic combustion wind tunnel based on variable frequency speed-regulating technology. The mathematical model which describes the characteristics of the system by analyzing the characteristics of all aspects of the system has been established. According to the flow control requirements and the mathematical model, we have carried out an analysis and comparison of the control effects of the oil-fuel supply system by using control law such as PID, Fuzzy-PID, and DMC. The simulation results show that DMC is the optimal control law.
