Virtual Control-Laboratory For Multidisciplinary EngineeringEducation

9352523 Crisalle该项目开发和实施了一个用于教授控制系统设计和分析的虚拟控制实验室(VCL)。该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、控制仪器以及数据采集和显示设备的虚拟设备。VCL的目标是让学生有可能探索不同的操作场景：他们可以实验改变不同控制参数的效果，在不同的制度下操作系统，并尝试替代控制配置。作为一种教学工具，VCL允许使用令人信服的现实环境来发展实践经验。VCL的主要吸引力在于，它实现了使用物理实验系统很难实现的教学目标，这些物理实验系统通常对激励反应缓慢，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所有控制应用基本上都服从于相同的分析和设计策略，VCL被设计为一种多学科工具。在这个项目中，VCL被用于向化学和电气工程专业的本科生教授控制技术。来自每个学科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。相关课程的内容将被修改，以纳入与VCL一起完成的实验。随后，将使用VCL对物理系统进行控制实验。在这些应用中，虚拟系统被停用，然而，控制器和显示设备保持不变，然后学生可以利用从虚拟系统实验中获得的先前经验。***

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. ***
