基于观测器的复杂动态网络故障诊断新方法

Observer-Based Approach for Fault Diagnosis of Complex Dynamical Networks

针对复杂动态网络拓扑未知情形,研究复杂动态网络故障诊断问题。基于观测器思想,提出一种复杂动态网络故障诊断新方法。该方法只需利用网络节点输出信号进行观测器设计,克服了现有方法利用节点状态变量设计观测器存在的不足。研究表明,这种方法能够监测网络拓扑结构的变化。通过系统仿真,证明文中所提方法的有效性。

According to the case that the topology of complex dynamical network is unknown, the fault diagnosis of complex dynamical networks is studied. Based on the observer design, a new approach on fault diagnosis of complex dynamical networks is proposed, which only needs the output signals of nodes to design the observer, and can overcome the disadvantage of the existing methods using state variables of nodes to design the observer. It is shown that it can monitor any changes of the topology structure. The effectiveness of this method is successfully demonstrated by simulations.
