摘　　要：介绍了荷兰Twente大学控制工程系研发的先进控制实验平台的基本组成、功能和基于机电一体化设计软件20-sim。以先进控制演示仪为研究对象,在20-sim环境下建立了系统的图标化数学模型,并从理论上对模型作了降阶分析。根据系统辨识的模型参考自适应控制(MRAC)原理,编制了模型参考自适应和Lyapunov求解模块。采用线性二次型调节器为控制模块,构成了完整的先进控制演示仪的MRAC控制系统。该系统仿真结果显示所建立的模型针对性强,可用于各种先进控制策略的仿真研究。The fundamental construction and function of advanced control experimental platform developed by Control Engineering Group in University of Twente（The Netherlands） are briefly introduced in this paper.To take Advanced Control Demonstrators as the research subject,an icon mathematical model of the systems was constructed based on the modeling and simulation software 20-sim,then the theoretical lower-order approximation was made directly.Based on the principal of model reference control systems（MRAC） with system identification,the modulus for model reference adaptive control and Solving Lyapunov are developed here.Moreover,an icon model of the demonstrators is formed in the environment of 20-sim.Moreover,the whole Advanced Control Demonstrators MRAC modules is constructed directly by choosing Linear Quadratic regulator as the controller.The simulation results show the simplicity of the whole the constructed modules,and it provides a new way in the simulation research of advanced control theory.
