This paper is concerned with the distributed synchronization control of complex networks with communication constraints. In this work, the controllers communicate with each other through the wireless network, acting as a controller network. Due to the constrained transmission power, techniques such as the packet size reduction and transmission rate reduction schemes are proposed which could help reduce communication load of the controller network. The packet dropout problem is also considered in the controller design since it is often encountered in networked control systems. We show that the closed-loop system can be modeled as a switched system with uncertainties and random variables. By resorting to the switched system approach and some stochastic system analysis method, a new sufficient condition is firstly proposed such that the exponential synchronization is guaranteed in the mean-square sense. The controller gains are determined by using the well-known cone complementarity linearization (CCL) algorithm. Finally, a simulation study is performed, which demonstrates the effectiveness of the proposed design algorithm.
本文关注具有通信约束的复杂网络的分布式同步控制。在这项工作中,控制器通过无线网络相互通信,形成一个控制器网络。由于传输功率受限,提出了诸如减小数据包大小和降低传输速率等方案,这些方案有助于减少控制器网络的通信负载。在控制器设计中还考虑了数据包丢失问题,因为它在网络控制系统中经常出现。我们表明,闭环系统可以建模为一个具有不确定性和随机变量的切换系统。通过采用切换系统方法和一些随机系统分析方法,首先提出了一个新的充分条件,以保证在均方意义下的指数同步。控制器增益通过使用著名的锥互补线性化(CCL)算法来确定。最后进行了仿真研究,验证了所提出设计算法的有效性。
