Problems solved by technology

However, the AADL modeling platform does not support the modeling, analysis and graphical simulation of hybrid systems
[0007] Therefore, due to the defect that the existing AADL-supported OSATE platform cannot build a hybrid system model, there is an urgent need for a flexible and easy-to-implement method that can realize the establishment of a hybrid system model in a modeling platform that supports AADL

Embodiment Construction

[0045] The present invention will be further described in detail in conjunction with the following specific embodiments and accompanying drawings. The process, conditions, experimental methods, etc. for implementing the present invention, except for the content specifically mentioned below, are common knowledge and common knowledge in this field, and the present invention has no special limitation content.

[0046] Such as figure 1 As shown, the method for creating, analyzing and simulating a hybrid system model based on AADL of the present invention comprises the following steps: Step S1: set up a hybrid AADL model; Step S2: carry out lexical and grammatical analysis to the hybrid AADL model; The model is converted to a Modelica model to obtain a hybrid system model; Step S4: Perform graphical simulation on the Modelica model to generate a graphical simulation result. Each step is further described below.

[0047] Such as figure 2 As shown, step S1 includes the following...

Abstract

The invention discloses an AADL-based method for establishing, analyzing and simulating a hybrid system model. The method includes the following steps that a sublanguage hybrid AADL is established, and a hybrid AADL model is built through the sublanguage hybrid AADL; morphological and grammatical analysis is performed on the hybrid AADL model; the hybrid AADL model is transformed into a Modelica model, and the hybrid system model is obtained; graphical simulation is performed on the Modelica model, and the graphical simulation result is generated. Through the method, an extension sublanguage of the AADL is established so that the hybrid system model can be built, analyzed and simulated graphically on an OSATE platform.

Description

technical field [0001] The invention belongs to the technical field of software development, in particular to a method for creating, analyzing and simulating a hybrid system model based on AADL. Background technique [0002] The MDA (Model Driven Architecture) technology proposed by OMG (Object Management Group, Object Management Organization) in 2002 was born in response to this demand. The solution proposed by MDA is to separate the application system from the implementation technology platform, and use the unified modeling language UML to express the platform-independent PIM (Platfarm Independent Model, that is, the platform-independent model), and then establish a model suitable for a specific platform. Model PSM (Platform Specific Model, that is, a platform-related model). By separating corporate and technological change, the correlation between the two is reduced. [0003] OSATE is a well-known open source tool that supports AADL modeling and analysis, and is a plug-...
