An Integrated Modular Design Laboratory for Electrical Engineers

9452032 Ahmed-Zaid这个项目的目标是为电气工程本科高年级学生开发一个模块化设计实验室。该实验室将基于物理的设备和组件集成在基于pc的数据采集和控制环境中。新的设计部分为在完整的工程设计中快速开发和实现硬件和软件提供了一个集成的系统方法。本实验室的教学目标是教授电气机械、电力电子和固态器件、电力驱动、电机控制和机器人的基础知识，并将可靠性技术纳入可选设计解决方案的评估中。实验以系统为导向，建立在稳定性、反馈和模拟/数字控制器设计等概念上。微处理器控制和现代仪器一直强调在现实世界环境中对设计进行性能评估，受到建模错误，干扰，测量噪声以及传感器和控制系统故障的影响。四个初始设计部分围绕八个基于pc的数据采集和控制（DAC）工作站构建。每个DAC工作站由一台带有专用硬件/软件的486/PC和专用测试仪器（数字化示波器、信号分析仪等）组成。每个系统都配备了一个嵌入式高性能数字信号处理器（DSP）板，通过传感器I/O信号（编码器，霍尔效应器件等）与物理设备（电机，倒立摆，机械臂等）接口。DAC编程环境用于识别系统设备，并以模拟或实时的方式快速设计和实现经典和先进的原型控制器。

9452032 Ahmed-Zaid The objective of this project is the development of a modular design laboratory for senior-level undergraduate electrical engineering students. This laboratory integrates physically-based devices and components within a PC-based data acquisition and control environment. The new design sections offer an integrated systems approach for the rapid development and implementation of both hardware and software in a complete engineering design. The educational goals of this laboratory are to teach the fundamentals of electric machinery, power electronics and solid-state devices, electric drives, motor control, and robotics, with reliability techniques incorporated in the evaluation of alternative design solutions. The experiments are systems-oriented and build on concepts such as stability, feedback, and analog/digital controller design for various plants. Microprocessor control and modern instrumentation are emphasized throughout for the performance evaluation of the designs in real-world environments subject to modeling errors, disturbances, measurement noise, and sensor and control system failures. Four initial design sections are built around eight PC-based data acquisition and control (DAC) workstations. Each DAC workstation consists of a 486/PC with specialized hardware/software and dedicated test instruments (digitizing scope, signal analyzer, etc.). Each system is equipped with an embedded high-performance digital signal processor (DSP) board interfaced with a physical plant (electric machine, inverted pendulum, robotic arm, etc.) via sensor I/O signals (encoder, Hall-effect device, etc.) A DAC programming environment is used for the identification of the system plant and the rapid design and implementation of prototype controllers, both classical and advanced, in either a simulated or real-time fashion.
