1 ECE475 Control System Analysis ABET Syllabus Catalog Data: ECE 475: Control System Analysis. Three (3) credit hours. Classical and modern feedback control system analysis and methods: stability, root locus, Bode plot, state variables, and computer analysis. Prerequisite: Textbook: ECE 326. Prerequisite topics: knowledge of Laplace transforms and Bode plots. Richard C. Dorf and Robert H. Bishop, Modern Control Systems, 12th Ed, Prentice Hall, Contact Hours and Additional Course Information: The course meets multiple lecture periods weekly with a total of 150 minutes of lecture contact per week. The course is an elective in the electrical engineering program and is an elective in the computer engineering option. Relationship of Course Toward Meeting ABET Student Outcomes: The course supports instruction for Student Outcomes A, B, D, E and G as required by ABET Criterion 3 and ABET Program Criteria. The relationships are indicated in the Course Learning Objectives. The course does not include direct assessment for Student Outcomes. Course Learning Objectives: To enable electrical and computer engineering students to use mathematical models to describe physical processes, understand the effects of feedback, design control systems to meet specifications, analyze feedback systems using root locus and frequency domain methods and use Matlab for computer aided control system design. At the end of this course, students are expected to: 1. Analyze linear system using Laplace transforms. (Outcomes A and M) 2. Analyze and design control systems using bode plots. (Outcomes A, B, and K) 3. Construct a transfer function model for mechanical systems involving linear or rotating motion. (Outcome A) 4. Construct a detailed block diagram model for a feedback control system. (Outcome A) 5. Write performance specifications for a control system in terms of its transient response, steady-state error, and disturbance response. (Outcomes A and C) 6. Determine the stability of a feedback system using the Routh-Hurwitz and Nyquist stability tests. (Outcome A) 7. Use Root Locus technique to analyze and design feedback control systems. (Outcomes A, C, and K) 8. Use Matlab and the Control System Toolbox to analyze and simulate linear feedback control systems. (Outcome K) 9. Work in teams to model given mechanical systems. (Outcomes A and D) Student Outcome Measure Assessments: The course does not include direct assessment for Student Outcomes. Contribution of Course to Meeting the ABET Professional Component:

SERC 3029B, phone: , Class Schedule: Class meets three times per week for 50 minutes per meeting. MWF 2:00pm 2:50pm, Bevill Office Hour: MWF 3:00pm 4:00pm References: Website: Computer Use: Class Exams: Homework: Pop Quizzes: 1. J.J. D Azzo and C.H. Houpis, Linear Control System Analysis and Design, 4 th Ed., McGraw-Hill, N.S. Nise, Control System Engineering, 6 th Ed, John Wiley & Sons, K. Astrom & B. Wittenmark, Computer Controlled Systems, Prentice Hall, The Web-site for this course is Students are expected to access this Web site frequently to obtain lecture notes and important information about the course, particularly periodic messages. The contents include no less than the PowerPoint lecture material, syllabus, assignments, projects, problem examples, solutions. The site contents will be updated frequently. Computer software such as MathCAD, MatLab, and/or LabView will be used in the class or lab. MatLab and MathCAD PSpice are recommended or required for design and analysis of all the homework assignments and design projects. In-class exams will be scheduled as the semester progresses. The final exam is scheduled from 3:30pm to 6:00pm on Tuesday, December 9, It will be comprehensive. No make-up exams will be given. If a student misses an exam with a valid excuse, then the final exam grade will be substituted for the missing exam grade. Students missing an exam without a valid excuse will receive a zero for that exam. Students missing two or more exams will receive a failing grade for the course. Homework will be assigned regularly during the term, and is due at the start of the class period. No late homework will be accepted. Students are encouraged to work together on the development of homework solutions. However, all submissions must be independently prepared by the submitting individual. Homework should be folded in half lengthwise with your name(s), section number, homework set number, and due date on the outside. Homework assignments and solutions will be posted on the course website. Pop quizzes are a possibility. They are typically administered to check students understanding of homework or project assignments, and they will be closed book and notes.

4 Simulation/Design Projects: Successful completion of instructor supplied simulation/design projects will be required for completion of this course. A report from each student will be required to complete the project. Specific details will be provided at the time the assignment is made. NO late projects will be accepted. Basis for Basics for Final Grade: ECE75 ECE593 Two in-class examinations (@ 20% each) 40% 40% Projects 8% 8% Homework 12% 12% Quiz 10% 10% Final examination 30% 30% Total 100% 100% Class attendance (bonus) 3% 3% Class Attendance: Academic Dishonesty: Plagiarism: Disruptive Behavior: Disability Accommodations: Lecture handouts will be available on the course website at or before the lecture day. Please review these lecture notes prior to class attendance each day. Students are expected to attend all classes and are responsible for all lecture material (Bonus 3%). All students in attendance at the University of Alabama are expected to be honorable and to observe standards of conduct appropriate to a community of scholars. The University expects from its students a higher standard of conduct than the minimum required to avoid discipline. Academic misconduct includes all acts of dishonesty in any academically related matter and any knowing or intentional help or attempt to help, or conspiracy to help, another student. The Academic Misconduct Disciplinary Policy will be followed in the event of academic misconduct. The University of Alabama is committed to helping students to uphold the ethical standards of academic integrity in all areas of study. Students agree that their enrollment in this course allows the instructor the right to use electronic devices to help prevent plagiarism. All course materials are subject to submission to Turnitin.com for the purpose of detecting textual similarities. The Code of Student Conduct requires that students behave in a manner that is conducive to a teaching/learning environment. Students who engage in behavior that is disruptive or obstructive to the teaching/learning environment will be subject to disciplinary sanctions outlined by the Code of Student Conduct. Disruptive/obstructive behavior is not limited to but may include the following: talking, use of cell phone, physical abuse, verbal abuse, threats, stalking, intimidation harassment, hazing, possession of controlled substances, possession of alcoholic beverages.
