Abstract

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
