研究了拉格朗日网络与有向图的非周期间歇钉扎同步问题。通过在不连续时间对一部分智能体施加线性反馈注入,可以调节所有由拉格朗日系统描述的智能体以遵循同步状态。基于非周期间歇钉扎控制,导出了一些简单而通用的同步判据。与已有的拉格朗日网络控制方法相比,该控制器具有以下优点:(1)控制输入不连续;(2)控制的智能体数量少;(3)不依赖于系统模型知识.作为一个直接的应用,结果说明了拉格朗日网络组成的六个两连杆旋转机械手。最后,通过不同钉扎方案的数值仿真,验证了所提出控制策略的有效性。
Synchronization of Lagrangian networks with a directed graph via aperiodically intermittent pinning control was developed in this paper. By applying linear feedback injections to a fraction of agents at discontinuous time, all the agents described by Lagrangian systems can be regulated to follow a synchronization state. Based on aperiodically intermittent pinning control, some simple yet general synchronization criteria are derived. Compared with some existing works on control problem of Lagrangian networks, the distinctive advantages of the proposed controllers here include: (i) discontinuous-time control input; (ii) only a fraction of agents to be controlled; (iii) independence on the knowledge of system models. As a direct application, the results are illustrated by a Lagrangian network composing of six two-link revolute manipulators. Subsequently, numerical simulations with different kinds of pinning schemes demonstrate the effectiveness of the proposed control strategy.
