Abstract

The invention discloses a software-defined event trigger control method for a large-scale network system under spoofing attack, which comprises the following steps: firstly, establishing a large-scale network control system model, and then introducing a dynamic weighted centralized event trigger mechanism; considering the influence of spoofing attack on network transmission data, and establishing a network attack model; a large-scale networked system model is improved based on a spoofing attack and dynamic weighted event triggering mechanism; and finally, based on a Lyapunov stability theory, obtaining a sufficiency condition for ensuring that the system is finally consistent and bounded, and obtaining an event trigger parameter and a state estimator gain by solving a linear matrix inequality. According to the method, the problem of management complexity caused by a centralized event triggering mechanism can be effectively reduced, the burden of network transmission is relieved, serious threats of spoofing attacks to a network control system are considered, and the data transmission efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of software-defined network control, and mainly relates to a software-defined event triggering control method for a large-scale network system under spoofing attack. Background technique [0002] With the development of communication technology, network control system has received extensive attention. In contrast to traditional control systems, system components such as sensors, controllers, and actuators in networked control systems are connected via wired or wireless networks rather than point-to-point links. This provides ease of installation, maintenance and adjustment, as well as increased flexibility, reliability and scalability. These advantages make the network control system widely used in different fields. At the same time, with the continuous maturity of component technology and the increasingly complex system tasks, the scale of the network control system continues to expand, and multiple subsy...
