AB - This paper investigates the temperature control of the heat air-flow wind  tunnel for sensor temperature-calibration and heat strength experiment.  Firstly, a mathematical model was established to describe the dynamic  characteristics of the fuel supplying system based on a variable frequency  driving pump. Then, based on the classical cascade control, an improved  control law with the Smith predictive estimate and the fuzzy  proportional-integral-derivative was proposed. The simulation result shows  that the control effect of the proposed control strategy is better than the  ordinary proportional-integral-derivative cascade control strategy.
