Problems solved by technology

[0006] However, on the one hand, many designers can only simply use MATLAB language without professional programming training, so it is difficult to write codes that meet the specifications; on the other hand , the code volume of many existing codes is very large, the original developers can no longer find or lack documentation, the code has become a black box, no one has the ability to understand the logic, and it is difficult to rewrite

Embodiment Construction

[0023] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0024] see Figure 1-2 , a real-time simulation method of MATLAB, comprising the following steps:

[0025] S1: First, provide a script execution engine running on the embedded real-time operating system to execute and load the user algorithm model script in MATLAB language; the embedded real-time operating system runs on the embedded hardware platform.

[0026] The embedded hardware platform uses a current mainstream desktop processor (such as the ninth generation Core processor) to run a mainstream embedded real-time operating system (such as RT-Linux or VxWorks, etc.).

[0027] The script execution engine runs on an embedded real-time operating system and is responsible for loading and executing user algorithm model scripts in MATLAB language.

[0028] S2: Implement the user algorithm model script. The user algorithm model script refers to the...

Abstract

The invention provides a MATLAB (Matrix Laboratory) real-time simulation method, which comprises the following steps: firstly, providing a script execution engine running on an embedded real-time operating system and used for executing and loading a user algorithm model script in an MATLAB language form; wherein the embedded real-time operating system runs on the embedded hardware platform; realizing a user algorithm model script, wherein the user algorithm model script is an algorithm model realized by a user through MATLAB language; the system comprises three modules, namely an initialization module Initialize, an operation module Step of each step length and an end module Finalize. The script execution engine firstly executes an initialization module Initialize and then starts a timer,sets the timing length to be a step, and executes an operation module Step in callback of the timer. The C / C + + code is generated without a code generation technology and directly runs on an embeddedhardware platform, so that the burden of designers is reduced. The working efficiency is improved.

Description

technical field [0001] The invention relates to mathematical software MATLAB, in particular to a real-time simulation method of MATLAB. Background technique [0002] MATLAB is a commercial mathematical software produced by MathWorks in the United States. It is mainly used for algorithm development, data visualization, data analysis, and numerical calculation. It is widely used in many fields such as scientific research and engineering calculation. MATLAB provides a programming language MATLAB language, an interactive environment using the MATLAB language, and a series of tools. [0003] Under the development process of model-based design, designers can first use Simulink for model simulation. In order to verify the real-time and effectiveness of the model, it can also generate C / C++, PLC and other codes, and even binary executable codes of various hardware platforms, and run them in real time on actual PC, MCU, DSP and other hardware platforms to realize the model timeline...
