Three-dimensional path planning for unmanned aerial vehicle based on interfered fluid dynamical system

Abstract: This paper proposes a method for planning the three-dimensional path for low-flying unmanned aerial vehicle (UAV) in complex terrain based on interfered fluid dynamical system (IFDS) and the theory of obstacle avoidance by the flowing stream. With no requirement of solutions to fluid equations under complex boundary conditions, the proposed method is suitable for situations with complex terrain and different shapes of obstacles. Firstly, by transforming the mountains, radar and anti-aircraft fire in complex te… Show more

“…By determining the inverse matrix of the coefficient matrix in equation (10), the general scheme of two point-block iterative method can be rewritten as (Evans [21,22]) Based on equation (11), the iterative scheme for the two point-block iterative method can be defined as (12) where It can be clearly observed in equation (12) that the calculations of ϕ (k+1) and ϕ (k+1) are completely independent. Thus, block iterative method is very suitable for parallel implementation.…”

“…Moreover, they offer a complete path planning algorithm, and paths derived from them are generally smooth. In the past, an exact method based on the HPFs were applied in many area of researches including ship navigation [5], trajectory control [6], space robot path planning [7], navigation of snake-like robot [8], UAV motion planning [9], marine vessel path planning [10], 3D motion planning for UAV [11,12], space exploration [13], etc. In robot navigation problem, the HPFs were successfully applied in various types of environments [14][15][16][17][18][19][20].…”
