In this paper the airspeed control in an open circuit wind tunnel for a velocity range from 5 m/s to 25 m/s is presented. The instrument used for the velocity measurement was a type L Pitot tube, differential pressure, absolute pressure and temperature transducers were used too. Open loop tests were developed in the wind tunnel to determine modeling it through the Toolbox for system identification of MATLAB® for the design of the reference speed control strategy. By the process of identification the PI controller that is capable of maintaining a variation of ±2% with respect to the set point was obtained.
