一种基于次优采样的路径规划方法

A sub-optimal sampling based method for path planning

Mahdi Morsali, Fatemeh Mohseni

摘要:

本文提出了一种求解非完整系统次优路径的搜索算法。为此,该算法开始对车辆的前部进行采样,并利用成本函数向目的地移动。利用自行车模型定义了非完整系统,并采用不同的积分方法对系统动力学进行了稳定性分析。为了减少计算时间,选择了一种合适的积分方法和一个合理的大步长。当树足够接近目的地时,算法返回路径,并且为了将树连接到目的地点,定义了使用单次射击方法的最优控制问题。为了测试该算法,对不同的场景进行了测试,仿真结果表明该算法是成功的。

英文摘要:

In this paper a search algorithm is proposed to find a sub optimal path for a non-holonomic system. For this purpose the algorithm starts sampling the front part of the vehicle and moves towards the destination with a cost function. The bicycle model is used to define the non-holonomic system and a stability analysis with different integration methods is performed on the dynamics of the system. A proper integration method is chosen with a reasonably large step size in order to decrease the computation time. When the tree is close enough to destination the algorithm returns the path and in order to connect the tree to destination point an optimal control problem using single shooting method is defined. To test the algorithm different scenarios are tested and the simulation results show the success of the algorithm.
