Abstract

The invention discloses a joint simulation method and system for a wireless network control system, and the method comprises the steps: combining network simulation software OPNET with system simulation software MATLAB, and designing a WNCS joint simulation system based on the OPNET and Simu l ink. Meanwhile, in order to more accurately simulate a real network environment, an MANET (Mobile Ad Hoc Network) routing protocol is added into the built joint simulation system, and the joint simulation method of the WNCS based on the MANET is designed, so that the joint simulation of the control system and the network environment under a network protocol framework is realized. According to the method, the characteristics of the whole WNCS can be truly simulated, a powerful verification platform is provided for the theoretical achievement of the WNCS, good expansibility is achieved, different types of WNCSs can be simulated by utilizing the platform, and according to the needs of users, the platform is modified and adjusted to a certain extent so as to realize the combination of WNCS joint simulation and other network protocols.

Description

technical field [0001] The invention belongs to the technical field of network system simulation, and relates to a simulation method, in particular to a wireless network control system joint simulation method and system. Background technique [0002] At present, the wireless network control system simulation methods established by scholars at home and abroad can be roughly divided into two categories. The first category is the extension of commonly used simulation software. There are generally two methods: one is to add network modules to the control system simulation software to simulate the network environment, and the other is to define the mathematical model of nodes in the network model And control algorithm to realize the simulation of the control system. [0003] Although the simulation tools based on the expansion of commonly used simulation software can realize real-time simulation of the control system and network environment at the same time, the scope of applica...

AI Technical Summary

Problems solved by technology

The main reasons include: the function of the added network module is limited, it is difficult to define the control system with large scale and complex structure in detail, etc.

[0004] Most of the currently developed co-simulation platforms do not consider network protocols, and cannot simulate large-scale systems

The node models in these simulation platforms are generally fixed, and point-to-point data transmission is carried out between nodes according to the preset transmission path, which cannot meet the mobility requirements of wireless network nodes, and cannot make the control system transmit data according to routing protocols

Most of the control systems considered are simple in structure, generally composed of a single controlled object and a single controller, and do not have the ability to simulate large systems
