Modeling, system identification and validation of small rotorcraft-based unmanned aerial vehicle

  • In order to realize the flight control system of small rotorcraft-based unmanned aerial vehicles (RUAV), a precise dynamics model is needed. A time-domain system identification framework was presented for AF25B RUAV. The modeling process considered the influence of fuselage, main rotor/stabilizer bar system and coupled dynamic derivatives. Then the on-board sensor and control system were designed and configured. Based on the real flight data which gathered under the radio controlled(RC) hovering fly tests, a liner time-invariant system model was obtained through the time-domain system identification method. The identification result was analyzed and proved that model can reflect the dynamic characteristics in hovering condition fully.
