摘要：AbstractThe problem of a planar vehicle moving on a surface, such as an aerial drone or small naval vessel can be treated as series of trajectory planning problems between way-points. While nominally the movement between each two four dimensional points (positions and velocities) can be treated as an 1D projection of the movement on the vector connecting the two points, in the presence of arbitrary disturbance, the full problem on a plane must be considered. The combined minimum-time-energy optimal solution is now dependent on the value and direction of the disturbance, which naturally affects the structure and completion of the movement task. In this work, we address the minimum time-energy problem of a movement on a 2D plane with quadratic drag, under norm state (velocity), and norm control (acceleration) constraints. The structure and properties of the optimal solution are found and analyzed. The Pontryagin Maximum Principle (PMP) with control and state constraints is utilized. Simulations supporting the results are provided and compared with those of the open-source academic optimal control solverFalcon.m.
