Abstract

The invention discloses a complex network synchronization control method under aperiodic DoS attack, and the method comprises the steps: firstly building a complex network system model and a synchronous error model, introducing an event triggering mechanism, building a network attack model based on the influence of the aperiodic DoS attack on network transmission data; designing a synchronization error model of the complex network under a non-periodic DoS attack and event triggering mechanism; utilizing a Lyapunov stability theory to obtain a sufficiency condition for ensuring the stability of a system index; and finally, solving a linear matrix inequality to obtain an event triggering parameter and a controller feedback gain. According to the method, network bandwidth resources can be effectively saved, the communication capability of a transmission channel is improved, and meanwhile, a networked system can be helped to keep stable operation when coping with network attacks; an event triggering mechanism is introduced, so that the burden of network transmission can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of network control, and mainly relates to a method for synchronously controlling complex network systems attacked by aperiodic DoS. Background technique [0002] In a networked system, the communication network can realize remote, flexible and economical control, but with the continuous surge of sampled data, network resources become more and more limited, resulting in system performance degradation. In order to alleviate the plight of limited resources, the event trigger mechanism is considered to be an effective way to save network resources due to its unique advantages. The main idea is that only when the corresponding trigger conditions are met, the current data can be transmitted, thus saving the network resource. In the past few years, many different event-triggered schemes have been applied to corresponding engineering systems, such as sensor networks, multi-agent systems, and so on. [0003] Despit...
