Unmanned helicopters are now used to spray agricultural chemicals and take aerial photographs. In the near future, the aircraft are expected to be used for a wide array of activities, such as rescuing and fire fighting. Then, an autonomous flight control using several sensors typified by GPS is expected. In this paper, system identification experiments for a large-scale unmanned helicopter have been carried out. The helicopter is compensated by attitude control that permits the experiments during the flight. Using input and output data, system identification results are shown through numerical analysis. Moreover, the effectiveness of the identified model is demonstrated through a position control based on the H/sub /spl infin// control theory.
