基于分区段优化方法的帆船绕标航行路径动态仿真

Dynamic Emulation of Sailing Path Around Race Marks for a Sailboat Based on Section Optimization

为便于在帆船绕标比赛中根据赛场环境变化选取最优行驶路径,介绍了分区段优化全航程路径的规划方法及基于模糊概念和进化理论的区段航行轨迹优化方法,在MATLAB环境下建立了赛场最优航行路径的动态仿真模型。该模型可以动态模拟帆船的航行轨迹,可在每一区间实现最优航向点的确定。仿真结果显示:在给定赛场环境参数下,模型能给出最佳航速下的最优行驶路径及最佳航向角。

This paper introduceds an optimal path planning method for a whole sailboat sailing around race marks based on section optimization to select an optimal sailing route according to complex marine environments and each section utilizes fuzzy concept and evolutionary programming to find the local optimal path. It sets up dynamic emulation model of optimal sailing path for a sailboat under the actual marine parameters based on Matlab. The model may simulize sailboat sailing dynamically and locate the best heading plots. Emulation results indicate the effectiveness of getting the optimal sailing routing, the best heading angels of sails.
