Office Hours 2:00-3:00 MW Pre/Corequisites: Corequisite - ECE 475 Location: Room 134, East Engineering Texts: Modern Control Systems, 10th edition, Richard C. Dorf and Robert H. Bishop, Pearson/Prentice Hall, 2005. Schedule The schedule for this course is can be found through the web address: http://haskew.eng.ua.edu/ECE476/ECE476.html. Pre-Lab Assignments For each laboratory exercise, you will be required to complete a pre-lab assignment. This assignment should be worked on engineering paper using only one side of the page. You will turn in the pre-lab assignment at the beginning of the corresponding lab period. Lab Participation Your laboratory instructor will grade your laboratory participation on a 10 point scale for each laboratory exercise. This grade will be provided to you when your graded lab report is returned. ECE 476: Control Systems Laboratory General Laboratory Information 2 Laboratory Reports For each laboratory exercise that is performed, you will be required to submit an informal laboratory report at your next laboratory meeting. Details on the preparation of these reports are provided later in this manual. Each student will submit their own report, and each report should be prepared independently. Failure to submit any laboratory report will result in failure of the course. Grading Final grades will be based on the following breakdown: Pre-Laboratory Assignments ...................... 15% Laboratory Reports ...................................... 75% Laboratory Participation ............................. 10% TOTAL........................................................ 100% A standard 10 point scale will be used. Any questions about grading must be brought to the attention of the appropriate graduate teaching assistant within 1 week of the date the material was returned. After such time, no grades will be changed. ECE 476: Control Systems Laboratory General Laboratory Information 3 II. Laboratory Logistics The Control Systems Laboratory, with a course value of 1 semester hour, is designed to provide the student with practical hands on experience in obtaining device models and observing the limitations of such models. In addition, the student will gain experience in the design and implementation of closed-loop control systems to meet specific performance criteria. The laboratory exercises have been designed to provide reinforcement and greater in-depth understanding of the topics covered in ECE 475, Control Systems Analysis. The first laboratory session will be introductory in nature. You will be briefed on the layout of the facilities and on operation of the equipment. No reports will be required from the lab introduction session. Each lab section will be divided into groups during the first laboratory period. Experiments will be performed in these groups. The ECE 476 laboratory equipment, manufactured by Quanser, is based on the National Instruments ELVIS platform used in other ECE laboratories. Quanser has provided a great deal of documentation on their hardware and software, and they have provided a number of laboratory experiments that will be used throughout the semester. The documentation is available to you when you are logged on to the College of Engineering network. A drive will appear under “My Computer” as Elvis on ‘Watto’(Z:). When you expand the drive, a folder entitled QNET and Q-Guide CD for v1.10 for LabVIEW 8.2.1 will be available. Expanding this folder will make available a sub-folder entitled QNET Interactive Learning Guide. Opening this sub-folder will make available the interactive HTML document entitled qnet_interactive_guide. When opened, this will make available all of the necessary documentation in a well-structured format thought Microsoft Internet Explorer. Prior to your first laboratory meeting, you should review several portions of the Quanser documentation. When you initiate the interactive guide, you should go to the Overview page. From this page, you should go to an review the Introduction, Getting Started, Control Practice, LabVIEW, and Motion Control sections. ECE 476: Control Systems Laboratory General Laboratory Information 4 III. Laboratory Safety Rules The Control Systems Laboratory constitutes a hazardous environment. As such, the following safety rules are to be stringently adhered to. Violation of any of these rules can result in serious injury to yourself or others. Laboratory instructors will enforce these rules to the utmost of their ability. However, the final burden rests with you, the student. Remember to always think SAFETY FIRST. 1) Never energize a laboratory setup without the instructors acknowledgment. 2) Always assume that a circuit is energized until you have verified otherwise. 3) Use only one hand to make electrical connections. 4) Do not touch bare metal in energized circuits. 5) Never enter the laboratory with wet or moist hands or feet. 6) In the event of an accident, take immediate action to de-energize any active circuits without jeopardizing your own safety. 7) Bring no food or drink into the lab. 8) No tobacco of any kind is allowed in the lab. 9) Do not wear loose clothing or dangling jewelry into the removed, and long hair should be tied up. 10) No horseplay will be tolerated. 11) Never work on a cluttered lab bench. 12) When finished with a piece of equipment, return it to the place where it belongs, regardless of who got it out. 13) Never touch moving parts of machinery. 14) Do not stand in the plane of rotation of belts, chains, drums, etc. 15) Consider the consequences of closing or opening a switch before you do it. lab. Neckties should be Again, this list of regulations can not replace good common sense. Please use the utmost caution in the electric machines lab. ECE 476: Control Systems Laboratory General Laboratory Information 5 IV. Laboratory Reports You will be preparing informal laboratory reports for each experiment in this course. Although they are informal, laboratory reports should be word processed an contain suitable graphics and other technical features as appropriate. Reports should be stapled in the upper left hand corner. Each informal report should follow the outline provided below: I. II. III. IV. V. Cover Page A. Experiment Title B. Date C. Name and Student Number D. Lab Section and Group E. Names of Lab Partners F. Signature Abstract (one page or less) A. Objectives of Experiment B. Description of Procedure C. Summary of Conclusions Procedure (presented in the order performed, probably as a numbered list with all necessary explanatory text) A. Circuit Figures B. Data Collected (graphs and plots are often useful) C. Answers to Questions Posed in Procedure Section of Lab Handout Conclusions A. Responses to Objectives B. Unexpected Results C. Correlation of Data Question Responses (solution only, but include explanations as needed) Laboratory reports will be graded out of 100 points. You will be graded based on technical accuracy, presentation style and quality, and completeness. Note that grammar, spelling, punctuation, etc., will be considered.
