EET 4732- Feedback Control Systems

EET 4732- Feedback Control Systems

Standard Course Outline (Updated: Spring 2009)

catalog Description: / EET 4732- Feedback Control Systems
Analysis of networks and control systems. Stability and Compensation considerations, root
locus, Nichols chart and Bode plots. Simulation techniques, systems components. 4(3,3)
Course prerequisites: EET 3716, Physics I, and Calculus I
Goals/Objectives of the course: / In recent years, automatic control systems have been rapidly increasing in importance in all
fields of engineering. The applications of control systems cover a very wide range, from the
design of precision control devices such as delicate electronic equipment to the design of
massive equipment such as that used for the manufacture of steel or other industrial processes. Microprocessors have added a new dimension to the capability of control systems. New
applications for automatic controls are continually being discovered. The objective in this
course is to provide general methods for analyzing, modeling, predicting, design, and
modifying the performance of circuits and systems both in time and frequency domains.
Course Outcomes: / CO1: Students will have basic understanding of Control Systems
CO2: Students will be able to do both time and frequency domain modeling
CO3: Students will have an understanding of stability, tracking and Steady-state errors

CO4: Students will have an understanding of compensators such as PID controllers.

Computer Usage: / The use of some excellent PC packages such as program CC and MATLAB is integrated into
the course for simulation, analysis and design.
Laboratory Exercises or projects: / Throughout the course, the lectures are supported by experimental work that make use
of the hardware and computer-aided facilities available in the department. The laboratory experiments are intended to help the students develop skills for control systems design and
set up as well as for obtaining useful data, interpreting the data, and reporting the results.
The course involves laboratory projects based on written instructions provided in advance.
Required Equipment: / Analog and Digital Computers, Servos, Multimeters and Oscilloscopes
Course Grading: / There will be three exams:
Exam 1 (2/26/2009) 20%
Exam 2 (4/16/2009) 20%
Comprehensive Final Exam (4/30/2009, 5:30-8:20 PM)35%
Laboratory projects 15%
Homework 10%
Library Usage: / Students are encouraged to consult library and Internet references to aid in researching course material and complete written projects.
Course Assessment: / Useful methods for assessing the success of this course in achieving the intended outcomes listed above:

CO1: Traditional exam and assignments

CO4: Laboratory projects, exam and assignments

Course Policies: /

Grading Objections:

All objections to grades should be made IN WRITING WITHIN ONE WEEK of the work in question. Objections made after this period has elapsed will NOT be considered, no exceptions.

Professionalism and Ethics:

Academic dishonesty in any form will not be tolerated. Violations of student academic behavior standards are outlined in The Golden Rule, the University of Central Florida's Student Handbook. See ttp:// for further details.
Per university policy and plain classroom etiquette, mobile phones, pagers, etc. MUST be silenced during all classroom lectures and exams. Those not heeding this rule will be asked to leave the classroom immediately so as to not disrupt the learning environment.
Additional Course Information, Policies and Expectations: /

Computer Skills/Usage

• Webcourses and e-mail will be used to communicate with students and disseminate materials and assignments throughout the course.
• When sending e-mail to the instructor and/or GTA, please begin the “Subject:” of the message with the following:
EET<space>4732<space
- space> means insert a space.
• Students are expected to have access to and be familiar with a word processing application (e.g., Microsoft Word) as all assignments will require its use.
• Students are expected to have access to and be familiar with Matlab.

Course Assignments

• All assignments are due on or BEFORE the scheduled due date and time. Absolutely NO late assignments will be accepted.
• All assignments must be submitted in class.
• All assignments must be submitted in a high-quality and professional manner. They should be well-written and understandable. The steps/methods of solving the problems should be clearly stated.
• Students are encouraged to collaborate outside of class to discuss and debate course concepts. However, all assignments MUST be completed and written up individually. Each student is required to turn in his or her own solutions. If the assignment has been designated a team assignment by the instructor, one copy of the assignment solutions containing the names of all team members is required.

Exams

All exams will be proctored in class.

Excusal from Course Assignments and Exams

• Excusal from submitting an assignment on-time:
- If an emergency arises and a student cannot submit the homework on or before the due date, the student MUST give notification to the instructor NO LESS THAN 24 HOURS BEFORE the due date and NO MORE THAN 48 HOURS AFTER the due date.
• Excusal from an exam:
- Excusal of a student from an exam due to an emergency such as student illness, family illness or death, etc. requires valid and provable documentation before the student is eligible for the makeup exam. The documentation must be given to the instructor NO LESS THAN 24 HOURS BEFORE the due date and NO MORE THAN 48 HOURS AFTER the due date.
- Notification must be given to the instructor NO LESS THAN 24 HOURS BEFORE the scheduled exam for all other excuses such as conference/workshops, business trips, etc.

Makeup Assignments and Examinations

• There will be no makeup assignments given.
• Makeup exams will be given towards the end of the semester, at a date announced by the instructor. The makeup exams may be different and more challenging than those administered on the original date.
