    Abstract
  • According to the requirements of high speed airflow thermal tunnel simulation experiment system for fuel supply system, a fuel supply system based on variable frequency speed-regulating and bypass proportional throttle valve regulating was designed. After the analysis of the characteristics of every subsystem, the mathematical model of the system was established. Focused on the characteristic of large pure time delay existed in flow feedback of the fuel supply system, a fuzzy proportion integration differentiation (PID) prediction control strategy was proposed. The simulations and experiments show that the proposed control strategy has met the demand of the high speed airflow thermal tunnel simulation experiment system for fuel flow control quality. And the control effect is better than conventional PID and fuzzy PID control strategy.
