A method of automatic model generation based on simulink

Abstract

The invention discloses an automatic model generation method based on Simulink. The automatic model generation method includes the steps of formulating a naming standard of system variables, building system equations according to the formulated naming standard of the system variables, calling a corresponding basic module in a Simulink model base according to the built system equations, carrying out standardized naming on the corresponding basic module automatically according to the variables undergoing naming standardization, building model frameworks according to the basic module undergoing standardized naming, forming a sub system of a system through each system equation, calling the corresponding basic module in the Simulink model base according to operation rules of the system equations, and generating sub-modules in the corresponding model framework of each sub system. Naming standardization is carried out on the variables and the basic module, the model is built according to the standardized system equations and the basic module, the model can be automatically generated, the styles of models are unified, and readability is high.

Description

technical field [0001] The invention relates to the technical field of simulation modeling, in particular to a method for automatically generating models based on Simulink. Background technique [0002] The Simulink modeling tool is a tool with a wide range of uses. It can build mathematical models of linear, nonlinear, real-time, and discrete systems. The models built by this tool can be used for mathematical simulation, and can also be compiled into C code and downloaded to real-time The simulator performs real-time simulation. Therefore, the Simulink model is widely used in various fields, such as: control system, power system, communication field, etc. [0003] At present, in the process of using Simulink modeling tools to model complex systems, designers generally use the basic modules provided by Simulink models, such as addition, integration, and differential modules, based on their own understanding of the physical characteristics of the system and description equati...

AI Technical Summary

Problems solved by technology

[0004] However, in the above-mentioned process of manually building the model, there are the following problems: 1. The workload of modeling will increase rapidly with the complexity of the system equations, and mistakes are prone to occur in the process of building the model

2. The layout and location of Simulink modules will vary with different designers, the style is not uniform, and the readability is poor

However, the work of sub-system module division is determined by the designer, lacks specifications, and when modules are to be replaced later, the modification workload will be heavy
