Dynamic Modeling and Simulation of Flapping Wings UAV

Flapping wing UAVs, or Ornithopters, are becoming popular compared to rotary wing because they are less noisy and durable while maintaining same maneuverability. Recent advances in small-scale flapping-wing microaerial vehicles have extended the capabilities of flight control for a number of applications, such as intelligence, surveillance, and reconnaissance activities. Ornithopters have not advanced to autonomous control because their lift and thrust are generated from the same flapping mechanism which couples the forces, unlike a fixed wing which has separate lifting and propulsions systems. In this paper, a state space model of an Ornithopter is studied and a pole placement control is implemented for its stability. In addition, the coupled motion dynamics of Ornithopter has been studied and a computed torque control algorithm is implemented. Furthermore, an Ornithopter is designed and the real-time test is also carried out in the outdoor. In future, an autopilot system with the developed control algorithm will be implemented for the autonomous flight.
