自主转向车辆的目的地点,同时避免障碍物的问题,被认为是。车辆被建模为一个单一的积分器在平面上,它是假设障碍物是未知的先验。控制律是一种极值搜索算法,它使车辆转向导航函数的最小值。在这个框架中,证明了几乎所有初始条件下的避障和实际一致收敛到目标点。最后通过数值算例说明了理论结果。
The problem of autonomously steering a vehicle to a destination point, while avoiding obstacles, is considered. The vehicle is modeled as a single-integrator in the plane and it is assumed that the obstacles are unknown a priori. The control law is an extremum seeking algorithm, which steers the vehicle to the minimum of a navigation function. In this framework, obstacle avoidance and practical uniform convergence to a destination point for almost all initial conditions is proven. The theoretic results are illustrated using numerical examples.
