基于最优控制的机动飞行器纯方位目标搜索

Optimization-based Control for Bearing-only Target Search with a Mobile Vehicle

Zhuo Li, Keyou You, Shiji Song, Anke Xue

摘要:

针对离散时间Dubins飞行器,设计了一种基于优化的控制器,使其仅利用方位测量就能尽可能快地接近位置未知的目标。为此,提出了一个双目标优化问题,该问题综合考虑了未知目标位置的估计和移动车辆控制到已知位置的性能,然后采用带归一化的加权和方法求解,并在此基础上结合目标位置的最小二乘估计给出了控制器.此外,控制器不需要车辆的全球位置信息。最后,仿真结果验证了所提出的控制器的有效性。

英文摘要:

This work aims to design an optimization-based controller for a discrete-time Dubins vehicle to approach a target with unknown position as fast as possible by only using bearing measurements. To this end, we propose a bi-objective optimization problem, which jointly considers the performance of estimating the unknown target position and controlling the mobile vehicle to a known position, and then adopt a weighted sum method with normalization to solve it. The controller is given based on the solution of the optimization problem in ties with a least-square estimate of the target position. Moreover, the controller does not need the vehicle's global position information. Finally, simulation results are included to validate the effectiveness of the proposed controller.
