Virtual Control-Laboratory For Multidisciplinary EngineeringEducation

9352523 Crisalle本课题开发并实现了一个用于教学控制系统设计与分析的虚拟控制实验室（VCL）。这种教育软件在个人计算机平台上得到支持，并使用面向对象的编程来生成代表物理系统、控制仪表以及数据采集和显示设备的虚拟设备。VCL的目标是让学生有机会探索不同的操作场景：他们可以尝试改变不同的控制参数，在不同的制度下操作系统，并尝试不同的控制配置。作为一种教学工具，VCL允许使用令人信服的现实环境开发实践经验。VCL的一个主要吸引力在于，它实现了使用物理实验系统难以达到的教学目标，因为物理实验系统通常对驱动反应缓慢，而且操作和维护成本可能很高。由于所有相关工程学科中的整个控制应用范围基本上都适用于相同的分析和设计策略，因此VCL被设计为多学科工具。在本项目中，VCL被用于化学和电气工程本科生的控制技术教学。每个学科中的一个代表性系统被建模为虚拟设备；然而，这两个系统共享相同的控制结构和显示设备。相关课程的内容将进行修改，以纳入使用VCL所做的实验。随后，VCL将用于在物理系统上进行控制实验。在这些应用程序中，虚拟系统是停用的，然而，控制器和显示设备保持不变，然后学生可以利用以前从虚拟系统实验中获得的经验。* * *

9352523 Crisalle The development and implementation of a Virtual Control Lab (VCL) for teaching the design and analysis of control systems is conducted by this project. This educational software is supported on personal-computer platforms and uses object-oriented programming to produce virtual devices representing physical systems, control instrumentation, and data acquisition and display devices. The objective of the VCL is to give students the possibility of exploring with alternative operational scenarios: they can experiment with the effect of changing different control parameters, operating the system under different regimes, and trying out alterative control configurations. As a pedagogical tool the VCL permits the development of practical experience using a convincingly realistic environment. A major appeal of the VCL is that it accomplishes teaching goals that would be difficult to attain using physical experimental systems that often respond slowly to actuations, and which may be expensive to operate and maintain. Since the entire spectrum of control applications in all relevant engineering disciplines are essentially amenable to the same analysis and design strategies, VCL is designed as a multidisciplinary tool. In this project the VCL is used to teach control technology to both chemical and electrical engineering undergraduates. One representative system from each of these disciplines is modeled as a virtual device; however, both systems share the same control structures and display devices. The contents of relevant courses will be modified to incorporate experiments done with the VCL. Subsequently, the VCL will be used to carry out control experiments on physical systems. ln these applications the virtual system is deactivated, however, the controller and display devices remain unaltered and the students can then make use of previous experience gained from experimentation with the virtual system. ***
