| Abstract: | The difficult problem of the automatization of measurement and CDntrol in the large low speed wind tunnel is an automatization of large power system and large angle control system. Nanjing University of Aeronautics and Astronautics is the first one to carry out an automatization of power system, angle control system and the total automatization of the whole system in a large low speed wind tunnel in China. The power system rea1izes the high control accuracy of the dynamic pressure for a long time delay with compensation adjustment method at special given value. The angle contro1 system carries automatization of large changeable angle control system into effect step by step ith special techniques by induction motor. |
