Abstract

The invention discloses a network control system co-simulation method based on NS3 and MATLAB. The method comprises the following steps: designing an overall scheme of a networked control system co-simulation platform; determining a collaborative simulation platform composition module of the networked control system and determining a collaborative simulation platform data exchange and transmissionscheme; establishing running environments of two kinds of simulation software in a linux operating system; designing a time synchronization scheme of the networked control system collaborative simulation platform; wherein the collaborative simulation system is a simulation system with strict requirements for real-time performance and time sequence. Two simulators need to be synchronously propelled for execution. Three collaborative simulation time synchronization schemes are designed, two of the three collaborative simulation time synchronization schemes are selected to be realized, the design of a synchronous interaction model is improved, then, each module program of NS3 is designed, an NS3 simulation script is designed, and finally, each module program of MATLAB / Simulink is designed.

Description

technical field

[0001] The invention relates to a method for co-simulating two different simulation software, NS3 and MATLAB, by designing a characteristic framework and a synchronization scheme. Background technique

[0002] A networked control system (NCS) is a control system consisting of a system to be controlled and actuators, sensors, and controllers whose operations are coordinated through a communication network, so NCS contains a coupled control and communication perspective. NCS's use of a multipurpose shared network to connect spatially distributed elements results in a flexible architecture and often reduces installation and maintenance costs. As a result, NCS has found applications in a wide range of fields such as industrial control systems and unmanned aerial vehicles (UAVs).

[0003] However, the existing simulation software is concentrated on the control system or communication network, and the simulation of NCS is also based on the redevelopment of a singl...
