Low-Cost and Super-applicability Digital Navigation and Control System of Super-size UAV

Considering the reliability and economy of super-size high-subsonic unmanned aerial vehicle (UAV), a digital navigation and control system with high flexibility and low cost is designed. The system adopts the optimizing control law design during the flying-off course, the technique of adjusting parameter self-adaptive and low-cost combinatorial navigation strategy, thus ensuring the performance stability, degrading the cost and extending the airspace and groundspace of the aircraft. Through the simulations and true flights, results show that the system can guarantee the attitude and altitude to be stable. The error between the flight path and the programming path is very small. All the performances of the system can be achieved.
