自动控制原理实践教学的改革与探究-以基于MATLAB实时控制的水箱液位控制实验为例

摘要

Automatic Control Theory is the core foundation course in theprofessional of information and control, its practical teaching program not only takes on the tasks of comprehending, consolidating, deepening the theoretical knowledge through the class teaching, but also is the link between theory and practical application. In the practical teaching program of Automatic Control Theory, Experiment System is constructed based on MATLAB Real-Time Control module: Controller is debugged in the Simulink Module of MATLAB, the control signal is sent to the physical object model by means of multi-function card PCI1711.This practical teaching methods could organic bond the theory knowledge and practical application. Not only Implemented control action to the physical object, but also avoided the complex programming problem in the traditional real-time control. The running and debugging of the system is succinct and visual, and the efifciency of experiment has been improved.%自动控制原理是信息控制类专业的核心基础课程，其实践教学环节不仅担负着理解、巩固、加深课堂教学理论知识的任务，同时也是理论与实践应用之间的纽带。在自动控制原理实践教学中，构建了基于MATLAB实时控制的实验系统：在MATLAB的Simulink下设计调试控制器，通过实时控制模块(Real-TimeWorekshop，简称RTW)将控制作用借助于PCI1711卡多功能卡送至物理对象模型以实现物理系统控制。该实践教学方式，实现了控制理论知识与实践的有机结合。既实现了物理对象模型的控制方法的研究，又避免了传统实时控制中复杂编程的问题，运行与调试简洁直观，提高了实验效率。
