The paper also presents a comparison of various flight control systems and the one, which is designed using H optimization with loop shaping under external wind and aerodynamic disturbances for a six degrees of freedom UAV in which the pitch and angle of attack are controlled by proper canard and elevon commands. Besides flight control systems, navigation system is one of very important systems in UAV, especially in the condition whereby GPS systems are unavailable or radio signals are jammed during flights. By incorporating the viscosity effects to the original vortex method, it can eliminate the problem in finding the solution in CFD analysis of unsteady flapping motions for a large number of flapping cycles by controlling the pitching moment amplitude, which grows over time with multiple flapping cycles.
