摘要/Abstract

摘要： 提出了一种有限元模型校正及降阶方法在炉体温控系统仿真平台设计中的应用。通过测试炉体响应特性,校正ANSYS有限元模型中的关键属性参数,建立实际炉体特性模型。采用Krylo子空间降阶法的软件mor4ansys对有限元模型进行降阶,并转化为状态空间表达式。利用MATLAB/Simulink搭建基于状态空间模型的温控仿真平台,对炉体温控进行模拟设计。以绝热量热仪温控算法开发为例,介绍了建模流程,并验证了可行性,为工程领域的应用提供了参考。

Abstract: A modification and model order reduction (MOR) method based on finite element model is proposed, which can be used in the design of simulation platform of furnace temperature control system. Based on the step response test of furnace behavior and the modification of finite element model's key parameters in ANSYS, the model reflecting the actual characteristics of furnace is obtained. Based on the software tool called mor4ansys using Krylo subspace reduction method, the state space model is obtained. The MATLAB/Simulink simulation platform based on state space model is built for more research work on furnace temperature control design. Based on the research of control algorithm of adiabatic calorimeter, the modeling process and the feasibility verification are described. The simulation research provides a reference for the application of engineering.

Key words: model modification, MOR, state space, temperature control simulation, adiabatic calorimeter
