摘要:

研究了平面上一组移动Agent的编队控制问题,其中每个Agent被建模为一个运动学点,并且只能使用其局部框架中的局部测量。代理人需要保持一个几何图案,同时保持一个所需的距离,一个静态/移动的目标。该算法的预定构形是一种通用构形,可以是任意几何构形,N-agent系统的相邻关系只要求包含有向生成树。针对编队控制问题,基于解耦设计思想,提出了一种分布式控制器。该控制器的一个优点是它只使用每个智能体在其局部坐标系中的局部测量值,从而成功地解决了实际多机器人系统缺乏全局坐标系或共同参考方向的实际问题。考虑到实际机器人应用的另一个实际问题,采样数据是可取的,而不是连续时间信号,基于采样数据的控制器的开发。理论分析了多智能体系统在具有静态/移动目标的连续时间控制器和具有静态目标的基于采样数据的控制器下收敛到期望编队的问题。通过数值模拟验证了控制器的有效性和性能。

英文摘要:

We study the formation control problem for a group of mobile agents in a plane, in which each agent is modeled as a kinematic point and can only use the local measurements in its local frame. The agents are required to maintain a geometric pattern while keeping a desired distance to a static/moving target. The prescribed formation is a general one which can be any geometric pattern, and the neighboring relationship of the N-agent system only has the requirement of containing a directed spanning tree. To solve the formation control problem, a distributed controller is proposed based on the idea of decoupled design. One merit of the controller is that it only uses each agent's local measurements in its local frame, so that a practical issue that the lack of a global coordinate frame or a common reference direction for real multi-robot systems is successfully solved. Considering another practical issue of real robotic applications that sampled data is desirable instead of continuous-time signals, the sampled-data based controller is developed. Theoretical analysis of the convergence to the desired formation is provided for the multi-agent system under both the continuous-time controller with a static/moving target and the sampled-data based one with a static target. Numerical simulations are given to show the effectiveness and performance of the controllers.
