Lecture: TuTh 12:30-1:20pm in MSEE B012 Office Hours: TuTh 11:00-12:00pm REQUIRED TEXT: Feedback Control of Dynamic Systems, G.F. Franklin, J.D. Powell, and A. EmamiNaeini, Addison-Wesley, 5th Ed., 2006. REFERENCE: Modern Control Engineering, K. Ogata, Prentice Hall, 5th Ed., 2009. Control Systems Engineering, N.S. Nise, John Wiley & Sons, 5th Ed., 2007. Modern Control Systems, R. Dorf and R.H. Bishop, Pearson Prentice-Hall, 11th Ed., 2008. PREREQUISITE: ME375 GRADING POLICY: Homework and Pop Quizzes 20% Midterm 20% Final Exam 30% Lab 30% HOMEWORK POLICY: Problems are normally assigned each Tuesday and due one week later. Homework is to be handed in at the beginning of class on the day it is due. No late homework will be accepted. There will be an average of one homework set per week. Since assigned homeworks are an integral part of transferring course content to students, they are to be individual effort. Each new homework problem must begin on a new page. The homework format must follow the example attached to the syllabus. Homework regrades must be requested in writing within one class period after its original return. Students must receive a passing homework grade to pass the course. Finally, your lowest homework assignment will be dropped from the final average. EXAMINATIONS: There will be one midterm during the semester (See syllabus for time and location). All exams will be closed books and closed notes. You are allowed to bring ONE letter size hand written single sided "cheat sheet" to the exam. Graded exams will be returned as soon as possible. Exam regrades must be requested in writing within one week after its original return. There will be no make up examinations. The final exam will be comprehensive. Time, date and venue are to be announced. LABORATORY POLICY: The laboratory grades will be determined by your lab instructor and will be combined with the test and homework scores at the end of the semester to generate a semester grade. Students must receive a passing lab grade to pass the course.

CAMPUS EMERGENCIES In the event of a major campus emergency, course requirements, deadlines, and grading policy are subject to changes that may be necessitated by a revised semester calendar or other circumstances beyond the instructor’s control. Any changes to the course will be announced on the course webpage. Consult http://www.purdue.edu/emergency_preparedness/ for emergency preparedness. If you are ill with flulike symptoms, such as fever, cough, sore throat and body aches, stay home and, if symptoms worsen, contact your health-care provider. The incubation period for the H1N1 flu is normally 24-48 hours, and the contagious period lasts for seven days after the onset of symptoms. Alert instructors via email that you will be absent for that period and provide a medical release proof upon returning. Arrangement will be made to the grading policy to accommodate your absence during the period so that you will not be adversely punished for the course. COURSE WEBPAGE: http://www.itap.purdue.edu/tlt/blackboard/ login using Career Account username and password. Then select ME475 and go to the course website. COMPUTER USAGE: Students will be expected to use MATLAB for some of the homework assignments. You are expected to secure a computer account having MATLAB within the first week of class. There is a self-paced MATLAB tutorial on the Web. It is strongly advised that you go through the corresponding tutorial during the course. The tutorial can be accessed through: https://engineering.purdue.edu/ME475/ctm/ TEACHING ASSISTANTS: Tyler Davis (Lead) 494-5961 ME36 [email protected] Radhika Bali (Tutor) 430-1568 ME140 [email protected] Lu Lu 586-3761 ME322 [email protected] James Mynderse 743-9271 ME248 [email protected] OFFICE HOURS: Mon Tue Wed Thr Fri 7:30-8:30
