Modeling and Smart Property Analyses of Variable Thrust Axis Based UAV

A general model of a variable thrust axis based unmanned aerial vehicle (UAV) is built and it is different from the common UAV. According to the theory analysis, the introduction of the variable thrust axis technique can improve the maneuverability and the agility of UAV. A hybrid longitudinal attitude controller is designed by combining the aerodynamic rudder control and the variable thrust axis control, and the control of the described nonlinear model based UAV is simulated. Simulation results show the superiority of the hybrid control strategy. The variable thrust axis based UAV has better smart properties compared with the common UAV.
