本文研究了仅利用相对方位和速度测量的领导者-跟随者编队控制问题。基于方位的领导者-跟随者控制策略通常使用固定控制增益,其保证的收敛速率显式依赖于期望编队的持续激励(PE)特性。我们提出了一种时变矩阵增益,该增益根据每个跟随者可获得的方位信息进行演化,并将收敛速率与PE界解耦。我们建立了所提增益在方位持续激励编队下的适定性和一致有界性,并通过一个可调设计参数刻画了指数收敛速率。所提出的控制设计进一步扩展到具有双积分器动力学的领导者-跟随者编队。仿真实验展示了与固定增益设计相比的收敛性能。

英文摘要

This paper addresses leader-follower formation control using only relative bearing and velocity measurements. Bearing-based leader-follower control strategies commonly use fixed control gains, for which the guaranteed convergence rates explicitly depend on the persistence of excitation (PE) properties of the desired formations. We propose a time-varying matrix gain that evolves according to the bearing information available to each follower and decouples the convergence rate from the PE bound. We establish the well-posedness and uniform boundedness of the proposed gain for bearing-persistently exciting formations, and characterize the exponential convergence rate through a tunable design parameter. The proposed control design is further extended to leader-follower formations with double-integrator dynamics. Simulations illustrate the resulting convergence properties compared with fixed gain designs.
