Study And Development Of Web Based Simulink Modeling And Simulation System

With the rapid development of the Internet technology, the simulation system is transforming from the centralized system to the distributed system. Simulink provides a powerful function of graphical interactive simulation, which is an efficient approach to do modeling and simulation of the control system and simulate industry process. According to the distributed and low-cost new requirements of simulation and lack of web communication function for Simulink, this paper develops a web-based modeling and simulation system with technology of ASP and Java Applet as well as the analysis of Simulink model file in the Simulation and Control Integration Platform of the Liaoning key Lab of Advanced Control System for Industrial Equipment.In this paper, the logic structure, function structure and functional modules of web-based Simulink simulation system are designed. The system is based on three-tier B/S structure. Graphical modeling interface adopted the designing idea of MVC, and implemented with Java Applet. The Simulink model files are created with C# as script language for ASP.NET and are, simulated through the MATLAB interface on web server. Finally, the application of this system propose to the temperature PID controller design of the batch reactor proves its effectiveness.This system realizing the combination of the Web and Simulink with the powerful functions of interactive graphical simulation as well as enriching the web-based simulation theory and methods. It will not only add the mobility to the Simulation service of Lab, but also provide the experience accumulation for constructing the Web-based distributed computing and simulation system in future.
