Simulation technology study of the high/low temperature environmental simulation system based on MATLAB

A simulation scheme based on the platform of MATLAB software for the high/low temperature environmental simulation system (H/L TESS) is illustrated by an example of simulation project. The MATLAB simulation model library of the system is built for systematic simulation with the individual equipment as basic module, the equations such as state equation, mass continuous equation, energy conservation equation and momentum conservation equation as the foundation, and the MS-Function and masked block as the basic method. Then the simulation models of a real environmental simulation system are set up using the models of this library. The application software of the H/L TESS is developed by the technology of MATLAB graphics, ActiveX data transfer and dynamic data transfer. It is approved that the approach can effectively carry on planning and design of system simulation research and give both the research and the application software a good continuity and expansion.
