摘要:在 MATLAB 仿真软件平台上,针对高低温环境模拟系统,首先以建
立系统动态仿真模型为目的,以单个设备为基本模块,以状态、质量连续、能量守恒、
动量守恒等方程为基础,以 MS-Function 函数与封装模块为基本方法,建立了高低温
环境模拟系统 MATLAB 仿真模型库,然后在此基础上搭建了实际系统仿真模型,最后
采用 MATLAB 图形窗口、ActiveX 数据传输技术相结合的设计方法开发了系统仿真应
用软件. 实践证明该方法效率高,仿真研究及所开发的系统仿真软件都具有较好的扩
展性和延续性.

Abstract:A simuiation scheme based on the piatform of MATLAB software for the high/iow temperature envir-
onmentai simuiation system(H/L TESS)is introduced and iiiustrated by an exampie of simuiation project. Fist the
MATLAB simuiation modeis iibrary of the system is buiit for systematic simuiation purpose with the individuai eguip-
ment as basic moduie,the eguations such as state eguation,mass continuous eguation,energy conservation
eguation,momentum conservation eguation,etc. as the foundation,and the MS-Function and masked biock as the
basic method. Then the simuiation m
