Trajectory optimization of tail-sitter considering speed constraints
<|reference_start|>Trajectory optimization of tail-sitter considering speed constraints: Tail-sitters, with the advantages of both the fixed-wing unmanned aerial vehicles (UAVs) and vertical take-off and landing UAVs, have been widely designed and researched in recent years. With the change in modern UAV application scenarios, it is required that UAVs have fast maneuverable three-dimensional flight capabilities. Due to the highly nonlinear aerodynamics produced by the fuselage and wings of the tail-sitter, how to quickly generate a smooth and executable trajectory is a problem that needs to be solved urgently. We constrain the speed of the tail-sitter, eliminate the differential dynamics constraints in the trajectory generation process of the tail-sitter through differential flatness, and allocate the time variable of the trajectory through the state-of-the-art trajectory generation method named MINCO. By discretizing the trajectory in time, we convert the speed constraint on the vehicle into a soft constraint, thereby achieving the time-optimal trajectory for the tail-sitter to fly through any given waypoints.<|reference_end|>
