摘要

本文介绍了集总输入/分布输出系统形式的分布参数系统模型，并在COMSOL Multiphysics软件环境中采用有限元方法对玻璃熔融过程的温度场进行了建模。将得到的分布式特性导出到MATLAB & Simulink中，在MATLAB & Simulink中创建用于控制综合的集总模型和分布式模型。利用MATLAB & Simulink的分布式参数系统块集，布置反馈分布参数控制系统，选取PID控制综合方法，对熔融玻璃温度场的控制过程进行仿真分析。

FEM based modelling and PID controllers design for a class of distributed parameter systems

In the paper models of distributed parameter systems in the form of lumped-input/distributed-output systems are introduced and modelling of temperature fields of a melting glass process by using of finite element method in software Environment COMSOL Multiphysics is presented. Obtained distributed characteristics are exported to the MATLAB & Simulink, where lumped and distributed models for control synthesis purpose are created. By means of Distributed Parameter Systems Blockset for MATLAB & Simulink, feedback distributed parameter system of control is arranged, where for chosen PID control synthesis method, simulation of control process of temperature field of melting glass is executed and analyzed.
