基于物理平台的多变量控制系统设计与研究

针对工业控制中多变量控制系统的强耦合特性,在模拟仿真环境下进行的过程控制的研究与实际情况有很大差距的问题,提出了一种在YC-SX多变量过控实验平台上进行的对多变量系统的解耦控制。在研究过程中,通过这个实验平台搭建了四容水箱多变量控制系统实物模型;并且借助Matlab软件实现了对此系统的系统辨识和解耦控制。由研究结果表明,此四容水箱多变量系统耦合基本消除;并且这样的设计能够更接近于工程实际情况。

Multivariable Control System Design and Research Based on the Physical Platform

In the field of the industry control the controlled system is usually coupling. And the experiment of process control in the simulation environment has a big gap with the actual operation.So this paper presents a kind of decoupling control of the multivariable control system based on YC-SX multivariable control experiment platform.In the process of the research,the model of multivariable quadruple tank system is built by using this experiment platform.And the system identification and decoupling control of the system are realized by using Matlab software.At last,the result of the study shows that the coupling of the quadruple tank is basically eliminated, and the design can be more close to the actual situation of the project.
