Focusing on the transitional mode of tiltrotor UAV, which is nonlinear, strongly coupled and uncertain due to its complexity in layout, structure and aerodynamic peculiarity, a control strategy is designed and proposed. First, considering of the aerodynamics of rotor and its tilt machinery, the mathematic model of this kind of UAV is presented. Then, the reasonable anticipant global trajectory is...
Focusing on the control system of convertible UAV, which is nonlinear, strongly coupled and uncertain due to its complexity in layout, structure and aerodynamic peculiarity, a kind of control method based on extended-state-observer (ESO) is proposed. First, the dynamic model inversion technique based on reference model tracking is applied to linearize the object and eliminate the coupled factors....
