摘要
针对分散控制无法实现子系统之间的信息交换,将分布式控制应用于网络化系统,以期实现子系统之间的信息交换和提高网络的性能.利用Lyapunov函数法,分别给出了在传统分散控制和网络分布式控制下的整个网络化系统稳定性的判据;给出了可容许的最大时滞的优化算法.将所得到的理论结果,结合到一个简单的网络化系统,进行数值仿真.结果表明,与传统分散控制相比较,网络分布式控制更能提高整个网络化系统稳定性的收敛速度.
Replacing the decentralized control, the distributed control, is used for the networked system in order to achieve the exchange of information between the subsystems and to improve its performance. Based on the Lyapunov function method, the optimization algorithm for the maximal permissible time delay were derived in the case of a communication signal delay, and the stability criteria of the whole networked system were proposed respectively for the decentralized control and the distributed control . A simple networked system and the corresponding numerical simulation was couducted. By using the proposed theory. The results show that, compared with the traditional decentralized control, the network distributed control can improve the convergence rate of stability of the entire networked system.
