Abstract :
By reasonably predigesting the characteristics of the subminiature rotorcraft, a model for a subminiature rotorcraft is established and the linear time-invariant attitude dynamics with physical parameter of the subminiature rotorcraft at hover is obtained. A subspace-based state space system identification method and analysis of model uncertainty is applied to the model of rotorcraft. At last, the valid of the identified attitude model is testified.
