In view of problem for miniaturizing Micro Air Vehicles (MAV), a novel asymmetrical pitch system faced to rotary wing MAV is introduced. The pitch mechanism and control characteristics are studied and analyzed. Because the deformation of elasticity link is key to generate the blade pitch, it is analyzed and calculated by elasticity finite element method. And the results illustrate the linear relationship...
By reasonably predigesting the characteristics of the subminiature rotorcraft, a model for the nonlinear dynamics of a subminiature rotorcraft is established. Through the linearization of the nonlinear dynamics, 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 is applied...
