This paper attempts to research the issue of in-flight icing identification of aircraft flight dynamics. A nonlinear aircraft dynamics model is set up to simulate the wind turbulence effect on aircraft. The effect on flight dynamics by icing and wind disturbance are compared with clean one. In non-steady atmosphere, it becomes not so easily to detect. So a(More)
The extreme aeroheating at hypersonic regime and the insufficient dynamic pressure in the near space limit the achievable performance of the hypersonic vehicles using aerosurfaces alone. In this paper, an integrated pneumatic and thrust vectoring control strategy is employed to design a control scheme for the longitudinal dynamics of a hypersonic vehicle(More)
The paper studies the exponential lag synchronization of a class of delayed chaotic neural networks with impulsive effects via the unidirectional linear coupling. Some sufficient conditions are derived by establishing impulsive differential delay inequality and using M-matrix theory. An illustrative example is also provided to show the effectiveness and(More)
The saucer UAV (Unmanned Aerial Vehicle) features both helicopter and traditional fixed-wing airplane, is capable of hovering, takeoff and landing vertically. The configuration of the UAV in this paper which is comprised of a propeller and there pairs of control vanes enclosed in the duct is new-style aircraft. In order to research the attitude control of(More)
