Evolutionary path planning for autonomous air vehicles using multi-resolution path representation
There is a recognized need for automated path planning for unmanned air vehicles (UAVs) and guided munitions. Evolutionary programming approaches provide an alternative to classical functional optimization methods with the capability of incorporating a variety of optimization goals, while tolerating vehicle constraints. In this work, we introduce an evolutionary flight path planning algorithm c...
متن کاملSmooth Trajectory Optimization in Wind: First Results on a Full-Scale Helicopter
A significant challenge for unmanned aerial vehicles is flying long distances in the presence of wind. The presence of wind, which acts like a forcing function on the system dynamics, significantly affects control authority and flight times. While there is a large body of work on the individual topics of planning long missions and path planning in wind fields, these methods do not scale to solv...
متن کاملIntegrated optimization of unmanned aerial vehicle task allocation and path planning under steady wind
Wind has a significant effect on the control of fixed-wing unmanned aerial vehicles (UAVs), resulting in changes in their ground speed and direction, which has an important influence on the results of integrated optimization of UAV task allocation and path planning. The objective of this integrated optimization problem changes from minimizing flight distance to minimizing flight time. In this s...
متن کاملA High-Fidelity Energy Efficient Path Planner for Unmanned Airships
This paper presents a comparative study of the effects of grid resolution, vehicle velocity and wind vector fields on the trajectory planning of unmanned airships. A wavefront expansion trajectory planner that minimizes a multi-objective cost function consisting of flight time, energy consumption and collision avoidance while respecting the differential constraints of the vehicle is presented. ...
متن کاملGuidance, Navigation and Control of Unmanned Airships under Time-Varying Wind for Extended Surveillance
This paper deals with the control of lighter-than-air vehicles, more specifically the design of an integrated guidance, navigation and control (GNC) scheme that is capable of navigating an airship through a series of constant-altitude, planar waypoints. Two guidance schemes are introduced, a track-specific guidance law and a proportional navigation guidance law, that provide the required signal...
